Edward is a wonderful host.
His studio makes one feel at home immediately. Tiny as it is, it serves all your needs.
There's a comfortable bed, a shower, a kitchenette with a microwave oven, a TV and (normally) Wireless LAN. There even is air-conditioning which might be helpful with a summer like this one.
The studio is only a few minutes from the next tube station and you can travel anywhere in London really quickly and without any problems. Even walking back in the dark felt okay in that neighbourhood.
Moreover, there is a number of shops near Edward's place, e.g. Tesco or Boots.
Edward is a very open person and easy to talk to. He is genuinely interested in Leopold and eager to help. On our last day we could leave our luggage until the afternoon, so that we didn't need to go to a station to leave it there. Thanks again!
I stayed for three nights with my seven-year-old son and I'm determined to come back soon.
