Great location, being right on the Thames and therefore walkable to many places.
Also, fairly useful to have a mini apartment, if staying for a while and needing to do washing, etc.
However, I didn't really like the layout of the room, as it felt very cramped in the bedroom part and didn't have much natural light. Also, there were no bedside lights (only very bright lights above your head). Right outside the window of the lounge part, was a big building site (no fault of the hotel), but it was noisy in the day. The AC's on the 2nd floor were broken. Check-in was fairly late at 4PM.
