Stayed there Sat night and was impressed with what I got for a 4 star hotel.
The hotel is brand new, the rooms are clean and the swiming pool and steam rooms are brilliant. I read in previous reviews that the rooms were noisy, specially the ones facing the rail line but as the rooms have 2 double glazed windows these rooms are actually quieter and there is no outside noise whatsoever. Yes, the hotel is 10 mins walking from Sloan Square station but it is a enjoyable walk.
Next time I stay in London I will stay in this hotel.
