We stayed 3 nights with familiy with kids and enjoyed the house. There is a lot of space, the decoration is really nice and the house is really convenient with everything you need : nice words to welcome you, kitchen with basic products and specially for you to avoid you to do shopping for breakfast.
Transport to go to central London could be much longer than others in zones 1 or 2 but it really worths it to be confortable and sure of where you will stay.
