Stayed here for a couple of nights, the room was very clean and a good size. I think you need to bear in mind what you are paying for this hotel, its cheap for central London and there are compromises to me made.
The location is excellent with Regents Park and Oxford Street 15 minutes away but we had a room at the front with single pain glass and we may as well have slept in the street. Very little sleep first night but remedied by ear plugs the following night.
I also had trouble with hot water, shower was fine because it was electric but the sinks... I ended up boiling a kettle. Wi-fi is free but a bit intermittent. I would probably stay again as long as I could have a room away from the road.More
