We have a very pleasant stay at Rory's home. The house itself was perfect for our little family. Rory wasn't physically there to host us, but he gave instructions how to check-in and communication with him was very smooth. He was also very accommodating to our requests.
Location wise it's situated in a residential area where there is street parking. The train station is a short walk (10min~) and near by there are grocery stores such as Waitrose and Wholefoods. There's a one or two convenience stores within 2 blocks if you needed something quick. For example, there's a nice shop "Co-op Food - Battersea" just 5mins walk away.
Tip for young families, Clapham Junction station is not super stroller friendly, I believe only a few train platforms have a lift/elevator and most do not, so be prepared to do a lot of carrying depending on your train line number. The trains themselves are spacious enough, though usually it's just 1 stop away to London.
Rory's home also has a lot of children toys and the backyard was just what we needed to keep our baby entertained.
All in all we would definitely consider staying at Rory's if we visit London again. Highly recommended!
