We had a great time in wilder's flat. I was looking for a green quiet place but still within a reasonable distance from central london. And we got parliament Hill in Hampstead at our door step. The closest Metro station was closed for repairs so we walked a bit. But after we learned to take a bus nearby, we could get to another metro station quite easily. Wilder was not in the flat when i arrived, but he had sent me instructions on where & how to get the Keys. And he also answered some text messages i sent him upon arrival with a few questions. So there was no problem there. Just note that one of the bedrooms (the smaller) has a futton, not a real bed. I slept there on the First night and had a bit of back ache the following Day. So in case you have back problems, agree with your travel mates that you sleep in the bigger room where there is a real bed. But other than that, the flat is great, in a really nice neighborhood, so we enjoyed it a lot.
