Great time with Adrienne and John. Their place is very easy to reach from Central London and Heathrow airport and the room is 100 times nicer than staying in a hotel.
I also took a private French lesson with Adrienne and I'd certainly recommend her tutoring if you get a chance while you're there. She explained some of the grammar I hadn't grasped properly at school and after an hour I felt I was starting to chat more confidently in French. This is my first experience with Air BnB but if the others are like this, I'm definitely a fan.
