Ali's place is amazing, not only the house itself but the garden, and the convenient location (you can travel to Kingston from central London using Oyster or contactless card, which works out cheaper). There are shops/restaurants, large supermarket, and a train station just around the corner. The neighbourhood is very beautiful and quiet; I particularly enjoyed working on my laptop at the garden table, and listen to all the birds singing.
Ali herself is an outstanding host, and if by any chance there is an issue with something, she knows how to fix it.
Hope to airbnb with Ali on my next visit!
