We only stayed one night at david's...unfortunately really, because he is a fantastic host and his house is ideally located to explore london. the house is only a 5 min walk to tube, overground and busses and therefore you can get into central london in only a few minutes. brixton market is just around the corner and there are venues for concerts (my purpose of coming to london ;) ) in really short walking distance. david seems really open minded and he was very friendly and supportive. he would give us advice on what to do around the area and his house (where he lives with his family who unfortunately we didn't meet) is very warm and welcoming with everything you need for a good trip to london. i would definitly stay there again! ...and the bread is awesome ;) !!!!!!
