My daughter and me are great fans of London, and we have already stayed in Airbnb accommodation there before. Our stay at Chris' place definitely added to all our positive experience. I think it pays off to look for a host with a "personal touch". We enjoyed our little chats with Chris and his wife. The room with bathroom (and the whole house) is very clean, the bed was super comfortable, we could store something in the family fridge. Chris also gave us useful tips about the surroundings.
The house is only a really short walk away from the tube, but yet in a very quiet neighbourhood, with shops, pubs and restaurants nearby. The pedestrian area of "Walthamstow Village" with some shops and restaurants we wouldn't have found without Chris telling us about this cute "hidden gem".
