I have used airbnb several times, and my/our stay at Hannah and Arjen's house stands out for several reasons. Specifically:
Communication leading up to our stay: Hannah replied within hours every time, and with very comprehensive answers. Impressive!
The stay: lovely house, receptive/ helpful neighbours. Incredible house. Thoughtful touches, welcome feel. Thorough guide/instructions. Modern inside, homely feel.
Access to central London is straightforward, and an enjoyable ride, but requires some homework to be efficient with your time.
Area: Crouch End (from what we saw of it) seems to have a lot of everything you might want/need.
Final word: we have a 4yo, and A&H's house was perfect for this. The toys and books were just perfect, and he enjoyed feeding the fish (or watching it being fed).
A VERY ENJOYABLE STAY.
