I stayed for a little more than a week and was very pleased with my stay, and the owners are nice and kind people. I was in London to prepare for an exam at the university and found that the studio is located in a nice and quiet neighbourhood, in Pinner, which really suited me for my study. The location is well deserved by public transports, but if you like to go out late in London, coming back after the subway is closed could be troublesome. The annex itself is small, but in good condition and has most of the things you would need for a prolonged stay. As already mentioned, I was really happy with my stay at this accommodation and can recommend it.
