We stayed for ten days in Francois and Lena's apartment and enjoyed our stay.
The apartment is huge! It is conveniently located close to Borough and London Bridge tube stations (10-15 minutes walk). Supermarkets are very close as is a local cinema, with half price tickets on a Tuesday. It is quiet and secure and we slept well on the comfortable bed.
We encountered some small plumbing issues and were unable to use the TV during our stay, as there was no aerial connected. Francois did his best to resolve these issues for us and it by no means spoiled our trip. He was communicative and replied quickly to any queries. Thanks!
