Tony's apartment is located in a quite residential area in the middle between two tube stations - Vauxhall and Stockwell. From Stockwell, you can either take the Victoria line or Northern line. Even though it's in zone 2, but it's convenient if you travel around London mostly using the tube/subway system. Right next to the Stockwell station is a Sainsbury Local which I found it very convenient too.
The apartment is a pretty "standard" London two-bedroom apartment, which you will be sharing with Tony and his wife. You will have your own private room. The room is big, spacious and clean, with a view of the courtyard inside the housing estate.
Tony and his wife are young London professionals. They are nice and easy going. Whenever I needed any advice before I came or during my stay, they very eagerly offer to help with suggestions. I stayed with them for 7 days.
