I booked Gill's place for my parents who came to London to visit me. It was perfectly located, close to where I live and with a great overland train connection into central London (Moorgate station).
Gill was very accomodating with the check-in time and welcoming on arrival. She is a great host. My parents enjoyed staying at Gill's place as it was clean, tidy and a quiet neighbourhood at night (which my parents liked). It was lovely to have Alexandra Palace park so close - best views over London!
I can recommend Gill's place to anybody who is visiting London and would like to stay somewhere less busy, but with easy access to the central london sights.
