We had a very pleasant stay at Edris' place. Our room was nice and clean, equipped with everything we needed.
Her place is quite a bit away from the center of London. To get anywhere it would take us roughly an hour. This means you can't get 'home' easily for a quick rest in order to go out again. Also you have to spend some extra money on the commute. On the plus side there is a bus stop right in front of her house and the night bus which connects to the center runs in walking distance.
Edris was a great host. She made us feel home. Her kitchen with supplies for breakfast was at our disposal. In our room we found guides and maps for London. Even sockets for all kinds of plugs were there. She really seems to care for her guests. And she was a well of information if needed! If closeness to the city is not a priority we would definitely recommend staying there.
