Martin and Petra: were lovely and very friendly, great to get to know. They helped us settle in and even made tea for us in the morning. Their place is very close to the nearest tube station, though people who stay there should be advised that the station has a lot of stairs and no lift, and Martin and Petra have the flat on the top level (so there are more stairs to the apartment as well, though Martin very kindly carried our bags up for us)
