I had a great time in London and in Hannah's house. She is a very attentive host and interesting person. Room is bright, clean and cozy, like the whole house with a little bit creaky floors (it's a good point I think), beautiful pictures on the walls and small garden in the back. The neighbourhood is quiet around the house, but not so far from it, you can find some nice places to spend time (even the old Nunhead Cemetery with great view and very misty atmosphere). Or you can easily go to the centre of London on train or bus, spend the whole day there and then go back and sleep good in tranquility. So I'm highly recommended Hannah as a host and a room as a place to stay!
