The room is in an excellent location, but I would not stay again in the same place if I could avoid it. The stairs are full of old and dirty carpets. During the night, I was extremely cold (heating not working?), so I had to sleep with my clothes and jacket on. The bathrooms are shared and not very nice. The place, in general, seems run-down. The price is not justified.
Positive thing: People working there are accommodating and you can keep your bags with them after the check-out so you can sightsee London.
