The apartment was good value and the situation was convenient so praise for that! However some points of information: The reviews relate to multiple properties serviced by Arnaud. We stayed at 15, Boulevard St Martin. It was interesting quaint and quirky BUT no external/opening window or ventilation in main bedroom except by opening the door (there was one fan in the flat)…. Also private club downstairs kept going with heavy bass just on the Saturday to about 5am which one of us could not sleep through. Another significant problem was that with 2 couples staying and having only 1 key and no key safe this restricted individual activities…. a portable aircon in the bedroom and an extra key or a key safe would solve the latter two issues! So if important to you, do check these issues beforehand with Arnaud. We did ask for an extra key on arrival but one was not provided.
