I enjoyed my stay at Nick's place in Camberwell. The place worked well both as a home base and to work out of for a couple days. Prince, the host's cat, is very welcoming as well.
The location isn't near a tube stop, but there are a couple buses nearby that are fairly convenient to get into central London with.
There's a washing machine, which is pretty convenient when you're traveling.
Instead of a traditional television, there's a projector with a fire stick for streaming.
