The room is spacious and cozy, and the house is lovely.
It also has Wi-Fi high speed Internet connection.
There is a bus stop (H37) across the road, connecting to St Margarets railway station and to Richmond tube station (district line) in few minutes.
At walking distance there is a nice path along the river Thames, which brings to Richmond.
A convenience store is just few steps from the house, as a few other stores which I didn't try.
10 minutes walking on St Margarets you will find the Ailsa Tavern, a pub which serves good dinners, which I loved.
Chi-chi is a very discreet landlord, and I really suggest this accomodation.
By the way, Richmond really deserves a visit! Great place.
