Very clean room, although very small. Has some nice amenities: small fridge, microwave, sink (in addition to the bathroom sink). Tight for two people. We were only in London for 1 night, though, and this suited our needs. Extremely well located--a few minutes walking from Tube station (Jubilee Line) as well as the Overground station. Lots of shops and restaurants nearby. Staff was helpful, but available on-site only during very limited hours: 9AM - 4PM. This could be problematic for some. They did stay an extra 5 min when we arrived late at 4:05PM (I called in advance), but they said normally they leave promptly at 4PM. Walls were a little thin, as we could hear our neighbors in the building.
Overall a pleasant stay.
