Great home - especially great beds, comfy with good linen. The house was very clean when we arrived. It is clearly not lived in day to day but just run for holiday letters, so it doesn't have a lot of personal touches. It has a good amount of space though, nice bathrooms and good heating. There isn't too much in the way of entertainment, unfortunately - great internet but no TV or similar. Would definitely recommend it if you want somewhere to use as a base for getting out and about - quick to central London and has everything you need otherwise.
Brett and his team were easy to communicate with and very quick to respond. We stayed over New Years so had (understandably) a bit more communication than usual to introduce ourselves and assure everyone that we weren't hosting any crazy parties, but it was very nice and simple otherwise.
