Matthew's house is really nice, as beautiful as in the pictures. The guest suite has everything you need for a couple and the kitchen is very well equipped. The neighborhood is also great: the Oval tube station (northern line) is only a few meters away (about 5 minutes walk), there is a Tesco supermarket nearby and a small market with food and drinks 24 hours. As for Matthew, he is an excellent host, who left us free to come and go at any time and kept a respectful distance, but was always available to answer our questions and requests. I strongly recommend his place and I'll try to stay there again whenever I go to London.
