The room is not small but the toilet + bath room is extremely small. When we sat on the toilet, the sink was just above my lap and my knees could touch the door. We also found that the bedsheet were just put on the floor outside the rooms before the staff changed them. I don't think the floor / carpet is clean. The room is spacious. The staff is friendly and helpful. The room was noisy (sound of aircrafts, ambulances, people at the bar at night time etc).
The points above are negative but there are positive things: close to Hounslow Central tube station (10 mins walk), lots of super markets, restaurants. It provides free parking and also the fee is low. Therefore, I shouldn't give them too low rating.
