I had very nice time at Timothy's house. Location is peaceful and close to the center. Since we are both musicians, we had common interest and it was fun to talk about music! I could use his kitchen facilities and since I like cooking, it was very good. Grocery store very near by. I just mention you, it is an old house from 19th centuries, maybe you will find some house dust which could be easily found in old buildings... When you search place to stay in London, I highly recommend Thimothy's house!
