We had a wonderful stay at Mark's flat. It was well suited for us, and it had everything we needed. Located close to several food markets, and even a health food store, which worked out perfectly for us, as we are vegetarian :)
Mark is a wonderful host, great positive energy, and a good sense of humor. We definitely would recommend staying here, it's a great place to stay when exploring the city. Oh, and it had a piano! Perfect for musicians!
