You must do something about that shower head. Limescale blocking shower heads, and killing off washing machines, is part of life for most British people. If nothing else, a manager might once per month unscrew each shower head, poke each hole with a pin and re-assemble.
Double room in the sense that one could just about walk past the double bed, but there was also a desk and a nice chair, albeit the room was not sufficiently wide for the chair to fit alongside the bed (helpful for my CPAP machine).
Nice fitted carpet. Good en-suite toilet, wash and shower room.
Television and WiFi worked well.
At about £27 per night, just inside the Central Zone and in a posher part of London, probably unbeatable value.
Co-op mini-supermarket round the corner very friendly.
