Paul is a great guy. The house was really clean, the bed really comfortable and he was very helpful all along the way. When I needed help with finding something he would be there to show me and my mother the route that we should take and he also suggests some great attractions that I wouldn't have thought if it wasn't for him.
His house is really close to every attraction. At the same time, it is a really quiet area where you will feel secure.
I would recommend going with Paul if you want to visit London for a few days.
