 Just that it was quite cold in the room and the hotel room has no proper window to ventilate air Maybe they do open the window at the top of the ceiling during cleaning but it was difficult for me to do it by myself 
 the room was kind of cold at first but i asked for the heating and they fixed it for me Initially the window in my room was broken and the hotel kindly changed my room to a bigger one The location is great it is about 2 minutes fast walk from Earls Court station Also it is very safe around the area I returned to hotel at 12 30am one day and felt completely safe
