Vivienne's house is fantastic. I attend a design conference every year in Greenwich, and this is the best place I've stayed in so far.
Located in a very nice and quiet area, the house is bigger than I expected from the pictures.
We were welcomed by John, who gave us a nice tour and made us feel at home.
We were from walking distance of the conference venue, and going through Greenwich Park was such a treat to start the day.
We couldn't get groceries done on the first day, so the fact there was coffee, tea, milk, bread and butter was more than welcome.
I'll probably be back next year if Vivienne's OK with it :^)
If you're hesitating, don't. The place is fantastic.
(there even is a Subuteo, that sparked memories from my childhood!!)
