Janus himself is by far the most attractive part of this location: a very friendly, smart, hospitable and a warm person. I spend a lot of fun time in the kitchen with him, discussing Important Stuff. The room was clean and light, but I hardly stayed in the room, since I was exploring London.
Hampstead is a beautiful albeit sleepy area with some good restaurants and pubs. It is just a few blocks away from Camden Town, for those who are interested in nightlife and markets.
Book the room immediately if it is available!
