It was not a good experience... The only good point about this room is the central location near to Piccadilly Circle, Chinatown. First of all, the room looked totally different than in the pictures. Much smaller and not so clean (there was human hair on the pillow and bedsheet). They have also many rooms on property and the room i got was not the one depicted on the listing.
Inside it looked more like cheap motel.
For short term staying, it is ok with good price for London, but i stayed there for a week. The room's window is close to a house wall full with air-conditioner outdoor units and ventilations from neighboring Chinese restaurants so each time you would like to have fresh air it smelled like food in the room, so i didn't even bother to open it. Eventhough i had work and didn't stay much in the room, it bothered me quite much. I would recommend this place for short term, but definitely not for a week.
