The entire apartment has several rooms on different floors, this room(#2) that I was in is above the front door and first set of stairs so when people come in or go out the room would literally be shaken when the door shuts. You can also hear the room above you(#3) talking easily. The heater in this room also makes loud ticking noises every 5-10 mins, if you're a deep sleeper should be fine but would be a bit difficult to first fall asleep. The room is also right above an Indian restaurant which could have some noise but would stop by around 21:30 (that was Sat night, on Sun was ok). The street is full of Indian restaurants, if you like Indian food it'd be great otherwise an English pub is also just around the corner. Otherwise, great location, very close to Euston station, Euston Square and Warren Street tube stations.
