Small, very, very, very small. We stayed on the "4th" floor, which is really more like the 8th. If you do not need something big and don't mind getting a workout this is the place for you. It was located only a few minutes away from the underground/train station. It was extremely clean. Only a few kms walk from parliament and other tourist places. Tons of restaurants within walking distance. We absolutely enjoyed our stay in London and would use the same apartment again without hesitation. P.S. Do not let the separate bathroom and shower throw you or keep you from enjoying this location. The bathroom was so clean and in great working condition.
