I highly recommend this place for your consideration. Wills is a great host. He goes to great lengths to ensure that your stay in comfortable. I happened to be in London on quite miserable wet days and always felt cold. Knowing this, Wills would turn on heating and prepare hot tea. I was very touched by this.
The room and the overall place is exactly as on the pictures. The flat is tidy and cosy. It is not on the ground floor though, so you do have to climb a few stairs up. Wills was kind enough to help me with my suitcase going up and down.
I would also like the stress the nice location of the house. Although it is not in walking proximity of a tube station, it is easy to reach by bus, which in my opinion is even better because buses in London have a good reach and is an excellent way to watch the city.
