Overall we had a pleasant stay. The flat is now obviously the family home, not a rental, as there were personal effects everywhere, and far more than in the photo's.
The location was excellent for tube stations, buses, walking to Hyde Park, convenience stores, pubs, restaurants and take aways.
The lay out of the flat is interesting, and we enjoyed having a couple of outside spaces to use (very rare in central London).
Noise was minimal which was great for central London.
Entry to flat is down some spiral stairs which won't suit everyone especially taking luggage up/down.
All in all a great location, and stay!
