Stayed for four nights all by myself. In a single room. No elevators but they'll help you with the baggage at the stairs. I liked the people who working there, very kind and friendly.
Shower booth was quite small even for me, an average weight Japanese female. It should be too small for most guys or people who think they are above average in weight. It may depends on rooms though. Both pressure and temperature was fine.
Not very fancy street but good access to several tube stations - Shepherd's Bush, Shepherd's Bush Market, Goldhawk Road and Hammersmith. There are a supermarket (Sainsbury's), a big shopping mall (Westfield) and cafe (Costa) in the street. You will find more around the stations. Good access to central London if you take buses.
