It was absolutely brilliant stay! Everything was perfect - apartment spacious and bright, view from windows, location (100m from Paris architectural and art pearl Centre Pompidou), close to the metro, lot of different restaurants right by the corner. Mare arrondissement- full of fancy places and people. Don't worry about 5th floor, stairs are wide and nice (you can bring your own piano with you:). Etienne was very helpful and friendly. Because of him we also enjoyed Normandy and found oysters in summertime! So, I definitely suggest his apartment for You. I hope to stay in his flat next year too! Thanks Etienne!
