I rented Carrie & Eoin's place for my family who was coming over from Sweden. My parents never used air bnb before so they were a bit nervous about the whole thing, but both Carrie & Eoin was so responsive in the messages and made the stay so very nice and we had such a wonderful time in London.
Location wise (a Londoner myself) it's easy to access to both overground and busses. I live in the east too so it was very convenient for my family to stay there. The flat itself is amazing, very very beautiful. Really, really recommend this place!
