Nice and clean room, not very big for three people (we knew it so not a big deal) and quite convenient for central London - like 5min walk + 20min underground.
The bathroom is shared with one other room and is located on the lower floor (clean and comfortable - very hot water).
The mattress for the third person is not very comfortable and is a bit sacrificed (especially if tall).
Very quiet area with small shops nearby and Marsha made herself available with flexible check-in hours.
We had no problems of any kind.
