Although I did not meet Andrew in person (his mother took care of letting the room) he was always extremely fast in responding to any message I sent to him.
The room is small, but very tidy and clean, with a lovely, modern bathroom. In short, the perfect place to stay when you're out strolling through London all day and most of the evening.
It's located right in the heart of Muswell Hill, with a large variety of shops and restaurants just round the corner of the street. In short: great place to stay when on a trip to London.
