Augustin has been an excellent host. He warmly welcomed us at the flat at the proposed time and gave us excellent recommendations to all the various things to do in BA. He was very forthcoming making taxi reservation etc.
The flat is exactly as described and is in a perfect location to explore BA. Public transport is close by and the neighbourhood is full of restaurants, cafes and clubs.
