Great location. As advertised and very quiet (which is quite rare for central London!).
The only thing I didn't like was the shower being 4 floors away from the room downstairs, although in fairness there was a toilet and sink upstairs. It had a sign saying it was private for my use only but it wasn't locked either so I don't really know if other people used the facilities. Would have been better if I'd had a key for it.
