The space was good value for the money with clean amenities and uncomplicated communication. We really liked the well equipped gym (free weights area, tread mills, rowers, TRX etc.), the good public transportation options and the views from the 12th floor over London. The restaurant downstairs (Mildreds) is definitely a recommendation! Reception was staffed 24/7 and receptionists were really friendly.
Be aware that the beds are really small for 2 people (bed size about 1.2m).
