It's a great place to stay in a very interesting part of Paris. It's not the typical Eiffel Tower view and walk along the river type of place, but very close to Metro lines, so getting into the city was easy.
The guests who stayed before us lost the key fob to open the gate, so we had to rely on paging Veronica over the intercom. That worked fine except for one night where we were waiting out on the sidewalk at 1 AM until one of her neighbors thankfully let us in. If that issue is fixed, I'd recommend this place. Otherwise, I absolutely cannot.
Communication was average at best. It would have been nice to have the check in information well ahead of time, rather than an hour before our arrival. For Americans traveling and relying solely on wifi, that was needlessly stressfully. It is also necessary for someone to meet guests outside the gate to show them how to get in. We literally never would have found the place if a kind neighbor hadn't offered to help us look.
