We were a group of 4 adults who stayed here for 4 nights. The apartment looks just like the photos. It's conveniently located within walking distance to 3 Metro stops. Filles du Calvaire, Oberkampf and Republique are all a 3 to 7-minute walk away, making the apartment a good base to explore the rest of Paris. Plus, restaurants and cafes abound in its immediate vicinity, so finding a place to have breakfast, coffee or a meal was never a problem.
The 2 larger bedrooms face a quiet courtyard and are quite comfortable. It's worth noting that the living room and single bedroom face Boulevard du Temple, which gets a lot of traffic (even in the wee hours) with noise levels that are audible even with the windows closed, so they might not be suitable for light sleepers. Also, the single bedroom's mattress is quite thin, making it (in our opinion) more suitable and comfortable for a child than an adult.
The apartment does not have any air conditioning, but the tower fans provided in each bedroom were more than adequate, even on days/nights that were a little warmer than expected for mid-October.
Communication with Ludovic was clear, easy and quick. We were especially thankful with his prompt responses on our last day when the washer/dryer broke down on us an hour before we were scheduled to check out... With our laundry stuck inside too! Ludovic sent someone over within 40 minutes and with his help, our laundry got rescued and we managed to catch our train to Brussels.
