Dave and his family were great hosts! You know you can count upon them if you need, or just enjoy their company. In the same time, they are a very easy-going family, and you will just have the space you need when you don't feel in the mood to chat.
The accommodation is exactly how it is described: you will get a clean, quiet place with an excellent price-quality ratio.
I am definitely grateful to this family for making my first stay in London as warm as a visit to friends would be!
