A really really good experience with Dave's flat ! The location of the apartment is perfect (Stoke Newington turns out to be a nice and fancy area ; the city center is easy reachable from here by the overground) and the flat itself is big, clean and modern !
Dave's instructions were very clear and helpful to find the flat and to discover the area, and he was nice enough to let us stay a few hours more since our train back home was in the evening :)
Highly recommended !
