I chose to stay in Balham because it was close to a friend's that already had guests.
Richard is very nice and keeps his place spotless. You have your own bathroom and did not use the kitchen as I was out exploring and eating out.
The room is simple, double bed, desk and a closet. And Richard had installed separate wifi in the room to make sure one has a strong signal. Living room has a huge TV if one wanted to watch a movie.
I will definitely recommend Richard's place.
