Jelena and her family are great hosts; very welcoming, warm and friendly. They treated my kids nicely and were even giving them toys and played with them.
The house was very clean. The room was fine and safe. I even did not the need to lock it. The area is quiet and you can really sleep well. We used our car to commute to Central London but it is possible to use a bus and then the tube as well.
I would definitely recommend them as a host.
