We had a great stay at Nick & Margareth's place for a long weekend in July. The flat is spacious, clean and well-equipped. We contacted our hosts when we reached the flat and they immediately arrived and showed us around. There's a large bedroom with a double bed, and a sofa in the living room that can be converted to a large single-bed. It was nice that there was also a large fixed sofa, so that we didn't really have to convert the sofa for use during the day. The flat is a 15 minute walk from Arnos Grove or New Southgate station, and so as long as you're ok with travelling 45min into/out of London at the start and end of the day, this flat is really ideal! We'll certainly come back next time we're in London!
