William is a very nice person. The correspondence with him was smooth. I've got all the information I needed and even more, his tips for what to visit in London and how to get to the center were really useful. The Blackheath/Greenwich area is quiet, nice and safe. The Greenwich park and the Greenwich observatory are just around the corner. The train to the city center is about 20 min walking distance (a wonderful walk through the Greenwith park) from the flat. The room is basic but cozy and clean. The kitchen is good equiped. If you need a quiet place to take a rest after a busy day in the crowded city of London, this is your place. Definetely recommend :)
