Jay's family has been my first London' new family. I've been there for a week and all what I can say is that they're awesome.
The room is clean, comfortable and nice. In the kitchen you can find everything you need. House's location is perfect: 8 min to uxbridge town center and underground station (metropolitan line tube 50 min to London).
They're such a nice family, ready to help you whenever you need something, open to other cultures, friendly and willing people: you will love them for sure.
