overall, I'm not an expert, but I believe it's a good bargain for London.
the room was quite small, smaller than I thought. it wasn't the same room that's shown in the pictures, but similar enough. room was super functional, but lacked a 'human touch'. the lights are too bright and 'cold', there's no reading or night light. but it's quiet and I was able to sleep well. contrary to description, there was no well maintained lift. (neither poorly maintained. there's simply no lift at all)
