This was my first airbnb experience and it has been pretty good.
Even though we, my brother and I, weren't able to see Nev during our staying (we met him the second last day), he has been very helpful and helped us to get into the house cause we had wifi and internet data problems and couldn't contact him. Apart from that, the house was extremely clean and to be honest pictures were worse than the real thing (the new ones match more the house). Moreover, even if he doesn't live in the house, he treats it like he does. The underground station is like 3 minutes walk from the house and it's on the Victoria line, one of the two 24h working underground on weekends. I definitely suggest to check here if you're planning a short holiday to London.
