Sally and Mathias were very helpful in making our stay a great one. They provided us with a book of maps and Mathias even loaned us a cell phone when mine did not get service. The bed was very comfortable and it was nice to have fixings for breakfast set out for us in the kitchen before we went exploring each day. The flat is very close to public transportation and Sally and Mathias gave us tips on hiring a taxi when we left. We would like to return and would recommend them as hosts for anyone visiting London - one small item to note is that there are several flights of stairs up to the flat.
