It was great! This nice house served all of our purposes: 4 couples, 3 nights, seeing a bit of London, visit some family and eat with Ottolenghi (he signed my cooking book).
It is clean and sufficiently spacious, there are clear instructions and the location is super. The subway is 5 mins away and takes you wherever you need to go, frequent trains from here. The hosts provided us with tea, coffee and all necessary food for the first period.
