Lorenzo gave a very accurate description of his flat and with check in instructions. I had a bit of an issue, but it was due to my not thinking clearly after the long flight. When I sat down and re-read the instructions my check in went like clockwork. The location is perfect especially if you will arrive from Charles de Gaulle airport via the Roissey Bus. My grown granddaughter and I stayed and we felt extremely safe in this building and appreciated the quiet atmosphere throughout the day and night.
