Great place to stay in London. So close to Kensington Garden, MANY shops and almost restaurants a few streets over (so hard to choose!)
Other guests were respectful with their noise levels at night and in the morning. Never had to wait for a bathroom.
Was a bit hot/humid because there was a bathroom attached to the bedroom, had cooled down by nighttime with the windows open.
I would highly recommend bringing a large travel towel or small blanket to use as a curtain for privacy (unless you happen to be on the top bunk)
I never had a need for the kitchen, but saw it getting plenty of use.
