Great place and great manager, friendly instructive and really amazing setup.
Nice location and nice private room and bathroom. Shower was a bit strange, it didn't have a usable holder for the shower nozzle nor a shower curtain. The manager seemed temperamental, from very nice and welcoming to upset and hostile over minor things.
They lost our reservation, waited a half hour while they figured out what to do. Then they gave us an "upgraded" room which was on the first floor, right next to the entrance and the trash room, there were loud noises all night, and we couldn't open the window without smoke coming in from the outside. The staff wasn't helpful, they didn't speak much English and didn't have any maps of Paris or any other supporting information. I will not return to this location any time soon.
