We stayed at the studio for two nights. Phil, who welcomed us, is extremely nice and helpful, despite us arriving before the regular check-in time. The flat is perfectly located in Belsize Park, was clean and the bed very comfy. Tanya, with whom I communicated beforehand was very nice and responsive as well, I haven't met her in person though. The only things we have to remark is that the walls in the house are very thin, we could hear the neighbours when we were in. We had a great time, thanks a lot!
