Andy's place is easy to find, not far from the tube and in a quite and safe neighborhood. He was very nice and helped us with good advice and equipment we forgot. His house is very cosy and we felt at home during the whole stay.
The area of East London is not as crammed with tourist as the inner city so all pubs, cafes and restaurant are quite affordable and within walking distance. The local people are really open minded and lovely, it was easy to have a chat here and there. We'd definitely come back and stay at Andy's again next time!
