Friendly staff and very clean. Convenient for Museums and Royal Albert Hall. Plenty of eating places around too. I stayed in a single room and the only downside was the tiny shower - I'm 5' 9" tall of average build and it was a very tight squeeze. That apart, would thoroughly recommend.
Hotel is very nice and clean, but there is a school next door with guys playing sports all day long and very noisy. Not their fault, but until about 2am someone kept opening the door near our room on the ground floor and it slams shut, maybe put a soft closer on that door
