We are two Spanish friends who went to London and spent some days in Christian's house. The host is really nice, he received me with a cup of tea and he explained me useful information about the transport and the area where we slept, Crystal Palace. The communication between Crystal Palace ans the heart of London is perfect. There are many overground trains.
The room is separated from the main house but it is in the same smallholding. A beautiful garden connects both houses.
From our point of view, we recommend it as a good accommodation to spend some days in London. The price is good and the house has everything we needed.
