I had a lovely stay at Lesley & Peter's flat. It is located in a good location. The hosts were very warm and welcoming. They even stocked the kitchen with food for breakfast. The flat was very comfortable and perfect for my week in London.
The bus stop is right outside the flat location and there is an overground station a few minutes walk. It was also located close to many restaurants and supermarkets. The neighborhood felt very safe, even during the early hours of the morning.
The only thing that I wish I had been warned about prior to booking is that the gate to enter the flat is quite heavy and difficult to open/maneuver if you have no arm strength or body weight, like myself, to pull on the metal gate in order to unlock it. Though I don't think this would be a big problem for most people and I did figure it out after a couple days.
