For me as a first-timer Zoe was the perfect host - welcoming, friendly and helpful. We were in contact before I arrived and much more so while I got lost searching for the flat (I should have read the instructions instead of trusting G Maps). The house is directly at a bus and near a tube station which is perfect for a tourist. The living rooms including the really superior bedroom I was in are to the back - an open, bright and quiet yard. The room Zoe rents out is just big enough for one with the very comfortable bed (the mattress does make a difference - no aching back!), a wardrobe and a chair. Everything I saw and used very tidy, clean and in good working order. No disturbance from the other flats.
If I have the chance for another visit in London I'll contact Zoe first.
