Our extended family of 8 stayed here for Christmas break and had a wonderful time. We had a few older guests with knee issues but accessing the rooms on the lower ground floor and going up to 1st floor were fine for them.
The home is very well presented and the furnishings are comfortable; what you see in the pictures is what you get. It's a great location, close to lots of activities, and less than 10 minute walk to the South Kensington tube stop, so getting around the rest London is easy.
I had to work a few days while there and the place had 2 small work stations set up, which was very convenient.
I would stay here again.
