Our family of four stayed at this hotel three nights in August. The room was adequate and met our needs as a place to return to at the end of the day and get a good night's sleep. Comfortable beds. Fairly good amount of space to store our belongings. Clean bathroom and great shower. Delicious breakfast each morning - yummy croissants! Working wifi. And friendly and helpful front desk staff.
The only real drawback was the street seemed a bit questionable in terms of safety - at least at night, especially near the Barbes Rochechouart metro station just around the corner. Though we found the location convenient to navigate the city (due to proximity of the metro), after the first night's return to the hotel, we attempted to avoid later arrival times at that station. The first night there was a throng of males (pretty sure they were drinking) that were all around the exit at this station.
Also, it would have been nice to have had a fan in the room as there was no a/c. We ended up closing the windows partway and rigging up some chairs to jam them to make it feel a bit more secure, so we could get a bit of a breeze at night.
Overall, we had a good experience and would be comfortable suggesting this to family or friends as a consideration and would consider it if we were to ever make a return trip.
