Great experience and good location...

Liked: This was a clean modern hotel with good access to the Tube and Hethrow airport. The staff provided good service. The hotel was a good value.
Disliked: I'd skip the fish and chips if you eat there. It was typical frozen food heated up. Try the chicken marsala instead. It was fantastic.

Superb

Superb

Exceeded our expectations

Liked: This hotel has a luxurious quality. The fittings are tasteful and very solid. There is a sense of space and elegance. The staff were exceptionally helpful and friendly. The room was large and the big beds were comfortable. The bathroom also had plenty of space and incuded a bathtub. Hot water was plentiful.
Disliked: The only drawback for some could be the distance from the Heathrow Terminals. The Hotel Hoppa shuttle bus was not reliable and did not follow the schedule. In our case, this was not an issue. We had a lot of luggage and would have needed to take a taxi, anyway. The Hilton Garden Inn is close to the Hatton Cross tube station. With light luggage, it is a convenient short walk.
