Staff was very helpful, but I should have asked for a room upstairs, not Room #1 downstairs and facing the street. The floors are very creaky--I wear earplugs but could hear person upstairs walking about. Upstairs (and in back) will also get you away from the street noise and car headlights. (It's a townhouse right on the street.)
Wifi was a bit inconsistent. On the other hand, workers came right away when I turned a knob too far and broke it (which would have kept me from using the shower).
Very convenient: frequent bus right outside goes right to Vauxhall (train and tube), Parliament, and Trafalgar Square and Charing Cross (train and tube).
