 The window in our room 510 was leaking some cold air from the street It was pretty uncomfortable No sleepers 
 Greatest thing about this hotel is that they give you an Internet phone that you can take with you around London and use for free I used my Facebook Skype Maps email etc A perfect thing for a foreigner Also very friendly stuff clean rooms Very good location 45 min by underground from Heathrow 3 min from the station to hotel 4 min walk to supermarket
