I think this flat is one of the best value for money one can find in London! Its location in Camden Town is perfect: not too noisy but lively, and there's a lot you can do around the Airbnb, even sometimes without taking any public transport (Camden Market, Koko Cafe, and its restaurant...). Public transportation (bus & subway stations) and several convenience stores are really close to the place.
The door code makes our arrival easier, and Hassan has been a very reactive host.
Sharing the common rooms (kitchen and bathroom) wasn't a problem, it was reasonably clean and not that busy even if we had to wait a couple of times for the bathroom.
I really recommend that place if you're intending to come to London!
