We loved this place for a couple reasons: Mostly we loved the quiet. It was a residential neighborhood and we expected noise from the area or the other flats that are connected. No problem. We actually liked the walk to the Underground each day. 20 mins each way but with 2 lines (Victoria and Piccadilly) you can quickly get anywhere. There is a walking / running trail within 50 meters of the house. Soft, quiet path that makes you feel like you are walking in a park. There is also within a 20 minute walk in the opposite direction of the Underground another Clock tower and restaurant area. We found excellent food there.
We only gave it 4 stars for clean. It was fully satisfactory but not sparkling clean and we had some fussing with the old key and lock on the very front flat door. It always worked, but usually required a minute of fussing with it.
We would book this place again, it was a good value.
