The best part about Oliver and Hellen's place is the transit location. While it is about an hour from the city center via tube, it's SO EASY to get there and back and buses run straight to the flat's street from the station at all times of day/night. Quiet neighborhood. It's a great place to stay if you love friendly, active kids (you might get a surprise visitor in your room!) and friendly hosts. Very accommodating and easygoing.
