Caveat Emptor
Description states 'hostel,' with shared rooms, and recent reviews including 'quiet,' and 'an upscale hostel.' Bargain for a last minute trip to Paris in a good neighborhood and new renovation are enough to take a risk.
Actual experience: Very much a traditional 'youth hostel,' so prepare accordingly. First four-bunk room, two separate times after 01:00 the two outstanding guests arrived strongly inebriated, both vomiting violently at length in the room's shared bathroom, before stumbling to their bunks, loudly struggling with their evening's decisions. This noise and stench overwhelmed the most robust earplugs and N95. Front desk moderately sympathetic, new room at 02:00 had only one other occupant until 03:30 [single room upgrade 221€], when two others loudly arrived, insouciantly making the room their own. Ample motivation to abandon hope of sleep, graze complimentary breakfast, evacuate hostel and wander pre-dawn Paris. No refund for canceling second night.
