A small room located on the first floor of a residential house. The host has several rooms to rent out. There is a common area with a microwave, coffee, tea, towels and two fridges. The shared bathroom is large and clean. I stayed one night there before catching an early flight from Heathrow. If you are staying longer be aware that the first planes land in Heathrow at 4.30 and Osterly is in the landing zone. The Host is very friendly and we had a pleasant conversation, when I checked in.
