I stayed here for one month. During this time Lucian has been a great host; always asking if I need help and trying to fix problems. The household was a bit old but with the help of detailed videos, I didn't get confused so everything was as it is stated.
And the environment is one of the best places to live in vicinity of Hampstead park (which is legendary, including swimming ponds, tennis courts, farmers market etc.), with lots of leisure activities, and shopping facilities within the walking distance. The bus station was in front of the house and The closest metro was 10 minutes by walk. I definitely recommend for long stays.
