It was a great experience, he is so nice, and an amazing host he offer us some cereal and that was a nice detail from him.
He is an amazing person and I totally recommend him, thank you for all!!
We were two and we enjoy the trip, it is in zone 3, and you will think is far away of the zone 1(center of London) but it's pretty near. We bought and Oyster card.
Also the bus stop is just outside of the house.
