Near the Airport and they had wonderful beds! Beautiful Down Comforters in clean cotton Duvets and Down Pillows - yummy. I can honestly say it was Better then Westin's Heavenly Bed! The location is great for an overnight layover at Heathrow, but not real close nor convienent for play in the city of London - lots of Airline Crew stay here. Nice Gym/Fitness Center too. And everything one would expect from the Marriott. Large rooms and bathrooms (by Americana standards). Nice dining, nice bars, nice lobby. And a difficult location...lol.
Comp - In room Coffee, tea, cocoa and newspaper. Ironing board and iron. Mini Bar.
Had a transit in London for 15 hours,so it was not worth going to city center,so I decided to check in this hotel,VERY clean,quiet and very comfortable.
