Nathan is the best. He had great suggestions about where to go and things to do, as well as suggestions for places to eat and things to see. He made my stay very comfortable and absolutely lovely.
Here are some pros:
Very near two tube stops, and reasonable walking distance to two more.
Great kitchen
Wonderful host
Nice bed and room
Great shower
I would recommend Nathan's as a stop for those interested in seeing the real city. A truly London flat.
