This cottage in Kew is very comfortable and homely. The space is very suitable for two people. I stayed at Rose's cottage with my young daughter who thoroughly enjoyed the large garden, which is beautifully planted and very generously, shared with Rose's guests.
It is a very convenient base (5 minutes to the tube station) for a stay in London. The Royal Botanical Gardens at Kew gardens are a short walk away and there is easy access to all the attractions of London - museums etc. Local restaurants are plentiful with adult and child friendly menus. The on-street parking is free (except for two hours on each weekday to deter commuters parking there) and there is lots of unrestricted parking in nearby streets.
Rose is a thoughtful host who provided everything that we needed for a comfortable stay. She frequently checked on us, but gave us enough space to feel like we were not intruded on.
I would definitely recommend Rose's place; it was a very pleasant experience for my daughter and I on our first trial of AirBnB.
