Not only will you save money there but you will have a pleasant stay, especially if you enjoy a comfy, simple, warmhearted welcome
Pluses:
Very friendly host
Very good location near the East Finchley tube station on the Northern Line which is particularly convenient to access the city, soho and St Pancras station
All necessary amenities: good bed, kettle, sink in the room to brush your teeth, wifi, good breakfast, very nice back garden, tv in the room
caveats: there seems to be a few guest rooms, hence the bathrooms can be busy in the early morning. My room on the street side was a bit noisy in the early morning but that did not stop me from sleeping like a log
Munch better value for money and so much more fun than a classical hotel !
