Great base for staying in central London, great communication also.
The amenities are good (lots of space to hang and store clothes, easy-to-use kitchen). Everything was clean and there is a nice calm feel in the apartment, despite being on a busy-ish road. It felt quiet and safe. Very close to central London attractions and the tube/bus to go further afield.
Not suitable if bringing bags up three flights of stairs is a problem for you!
