The hotel was nice, clean and in a good part of town. Very close to the tube (Circle/District lines). The hotel/rooms were clean and nicely appointed.
The rooms in the pictures are not representative of what we got. Please note that when they say that "some" rooms face Sloane Square and "some" rooms face the church... you may be looking down a small alley to a brick wall of the church. I could only tell when I looked at Google Maps that it was probably the church.
We rented a Twin room and the room was tiny with only a desk, night stand, luggage rack and a wardrobe with no drawers. The bed was similar to a futon in comfort, but the bedding was nice. This is not a hotel to stay in, it's one to sleep in.
Maybe the rooms average 215 sq ft, but ours seemed like it brought the average down. The bathroom was smaller than on a cruise ship (picture attached). The shower was under 1m square and the door may have opened 12 inches to let someone in. Don't drop anything on the floor if you're showering.
Oh, and don't mind the flat screen tv that covers part of the wardrobe and bathroom door. Something else to bump into in the middle of the night.
With that said, I won't stay here again. If I could ask for money back, I would. While the hotel was nice, this was the worst part of my trip.
