Uno Hotel Heathrow Windsor positions itself as a 4-star property in Slough, roughly four miles from Windsor Castle and about 8 miles from Heathrow terminals. But the hotel’s actual star rating varies across booking platforms – Trip.com lists it as a 3-star – and early guest feedback points to significant operational inconsistencies. This review sorts through the available evidence so transit travellers and Windsor visitors can decide whether this off-airport hotel fits their needs.

Who Are Uno Hotels?
Uno Hotels operates as a small hotel collection under the Uno brand. The Heathrow Windsor property, located on London Road in Slough, is one of its listed properties. On Instagram, the hotel describes itself as “centrally located at Slough a 4-Star Hotel … within proximity to numerous attractions and easy access to London.” The branding leans heavily on Heathrow and Windsor, though the actual location is roughly 8 miles from Heathrow terminals – not within walking distance.
The Uno Hotels Story
Publicly available information about the group is scarce. No official corporate website surfaced in our research. The Slough property appears to have been rebranded from a previous name (some booking platforms still list it under a “Langley Oak Hotel” legacy) around 2021–2022. This rebranding likely aimed to capitalise on the two major travel magnets – Heathrow and Windsor – that surround Slough.
Values and Hospitality Approach
From the limited social-media presence, the hotel projects a functional, no-frills ethos. Guest reviews, however, tell a different story. One reviewer on TripAdvisor described it as a “terrible, awful place,” citing rude front desk staff, a leaking shower, and minimal hot water. Two other reviews on Google repeat similar complaints about limited reception hours and maintenance issues. The gap between marketing language and guest experience is notable.
The takeaway: Uno Hotels appears to be a budget-oriented operator that rebranded a Slough property to attract transit flyers, but early guest satisfaction is low.
Uno Hotel Heathrow Windsor Reviews
Reviews are sparse – only 13 traveller reviews on TripAdvisor at the time of research – but the pattern is consistent: location works for some, but service and maintenance draw sharp criticism.
TripAdvisor Feedback Summary
On TripAdvisor, guest comments skew negative. Aside from the “terrible” review quoted above, others mention difficulty with check-in after 11pm (the front desk closes at 23:00) and a lack of hot water. No five-star ratings appear among the visible reviews. On Trip.com, the user score sits at 5.9/10 from 34 reviews, with the most recent ones pointing to cleanliness issues.
What Guests Appreciate
A minority of guests mention the convenience of the location for Windsor (8-minute drive to the castle) and the free Wi-Fi. Two reviewers on Google note that the room was “quiet” and the bed “comfortable.” These positive mentions, however, are outnumbered by critical ones. Because the total review count is low, even a few positive voices make up a larger share than at a busier hotel.
Common Complaints
The most frequent complaints across platforms include: limited front desk hours (closing at 23:00), self-check-in process (requiring a code obtained by phone), poor water pressure / temperature, and rude customer service. Two separate reviewers mention the shower leaking onto the bathroom floor.
The pattern: Uno Hotel Heathrow Windsor receives consistently critical feedback on service and maintenance, with location being the main redeeming feature.
Parking at Uno Hotel Heathrow Windsor
Parking is a common query among travellers considering this hotel. The available sources do not provide explicit confirmation of on-site parking or related fees. However, given that the hotel is located on London Road (a main road through Slough) and has no official shuttle to Heathrow, it is likely that a car park exists for guests. Booking platforms often list “free parking” or “on-site parking” as a filter option, but this is not verified by multiple sources.
On-Site Parking Options
The hotel does not mention parking capacity on its Instagram bio or in the Expedia description. One Google Street View image from 2023 shows a small car park alongside the property, but no official statement confirms its availability or cost. Given the location in a residential-commercial mix, street parking may be possible but is not guaranteed.
Alternatives for Parking Near Windsor
If you are using Uno Hotel as a base for visiting Windsor Castle, Windsor has several pay-and-display car parks (e.g., Alexandra Gardens, near the Long Walk). However, the hotel itself does not advertise a park-and-ride or long-stay arrangement. For airport parking, the official Heathrow parking lots are all on airport property – roughly 20 minutes away by car.
The catch: Parking specifics for Uno Hotel are poorly documented. If parking is a decisive factor, consider contacting the hotel directly or choosing a property with confirmed on-site parking.
What Hotels Can You Walk to From Heathrow Airport?
Uno Hotel Heathrow Windsor is not within walking distance of any Heathrow terminal. The distance from Heathrow (12.6 km) is roughly a 20-minute taxi ride or a 30-minute bus journey via the Hoppa service. This section clarifies which hotels are truly walkable and how Uno compares.
Hotels Within Walking Distance
Very few hotels are actually walkable from Heathrow. Those that are include the Sofitel London Heathrow (directly connected to Terminal 5) and the Hilton Garden Inn Heathrow (near Terminal 2/3 via the pedestrian tunnel). Some properties on Bath Road are a 10–15 minute walk to terminals, but Slough hotels like Uno are firmly off-airport.
Uno Hotel’s Walkability
Uno Hotel is located on London Road in Slough, a busy arterial road. Walking to Heathrow would take over two hours and is not feasible. The nearest station, Datchet, is 1.9 km away – a 20–25 minute walk. From Datchet you can take a train to Windsor & Eton Central or a bus to Heathrow, but the journey requires a change and takes about an hour.
Suggested Alternatives
For travellers who prioritise walkability to the airport, the Sofitel or Hilton Garden Inn are better options, though they cost significantly more. For those who want a balance of price and transit, the Delta Hotels by Marriott Heathrow Windsor (see below) offers a shuttle to Terminal 5 via the Hoppa bus, making it more connected than Uno.
The bottom line: Uno Hotel is not walkable to Heathrow. If you do not have a car, factor in taxi costs (£15–25 one way) or use the Hoppa bus (about £5).
Best for segments
Transit passengers
Uno’s location is not ideal for short airport layovers due to distance and limited shuttle service. However, if you have a long stopover and plan to visit Windsor, it may work.
Windsor tourists
The 8-minute drive to Windsor Castle is genuine. For budget-conscious visitors who drive, Uno offers a cheaper base than Windsor town-centre hotels.
Budget-conscious travelers
Room rates in Slough tend to be lower than at Heathrow-on-airport hotels. But weigh the saving against taxi costs to the airport.
Business travelers
Limited. No meeting rooms or business centre are mentioned. The Delta Hotels Heathrow Windsor (see alternatives) is set up for corporate guests.
Location and getting there
Uno Hotel sits at 19-21 London Road, Slough, SL3 7RL. The M4 motorway (junction 5) is about 2 miles away, giving quick access to Heathrow (exit 14) and central London. Datchet railway station is 1.9 km from the hotel – a 20-minute walk or short taxi ride. From Datchet, trains run to Windsor & Eton Riverside (10 minutes) and London Paddington (about 40 minutes via Slough interchange).
The hotel’s Instagram bio states “easy access to London,” which is fair by road or rail, but be aware that public transport from the hotel itself requires reaching Datchet or Slough station (2.5 miles). No direct bus stop is confirmed immediately outside the property.
Alternatives in set: Heathrow-area hotels
If Uno Hotel does not meet your needs, several alternatives in the Heathrow corridor offer different trade-offs. The table below compares key features.
| Hotel | Star rating | Distance to Heathrow | Shuttle service | Key highlight |
|---|---|---|---|---|
| Uno Hotel Heathrow Windsor | 3-star (platform) / 4-star (self) | 12.6 km | No dedicated shuttle | Lowest price point in Slough |
| Sofitel London Heathrow | 5-star | 0 km (connected to T5) | Walkway to terminal | Luxury convenience for early flights |
| Hilton Garden Inn Heathrow | 4-star | 0.3 km (T2/3 tunnel) | Path to terminals | Walkable to central terminals |
| Premier Inn Slough | 3-star | 10 km | No shuttle | Predictable budget chain standard |
| Delta Hotels by Marriott Heathrow Windsor | 4-star | 8 km (est.) | Hoppa bus to T5 | Largest property with meeting rooms |
Our pick: Which hotel should you choose?
For most travellers, the Delta Hotels by Marriott Heathrow Windsor offers a more reliable experience than Uno Hotel at a similar distance from the airport. Delta has 382 rooms, multiple restaurants, a fitness centre, 19 meeting rooms, and a shuttle to Terminal 5. Guest satisfaction on Marriott’s own site is solid – 4/5 for cleanliness and location – and its rates are often competitive for Slough.
If your priority is absolute minimum cost and you have a car, Uno Hotel may save you £20–40 per night compared to Delta. But the limited front desk hours, sparse on-site dining, and mixed reviews make it a risk for late arrivals or anyone needing reliable service.
Our recommendation for transit passengers: Book the Delta Hotels by Marriott Heathrow Windsor for a consistent mid-range stay with shuttle connectivity. For budget Windsor tourists who drive, Uno is a valid option, but confirm front desk hours and parking before booking.
