ADVANTAGES
Great location : city centre and at the heart of the Saint Michel district with several metro stations nearby.
Good reception : very flexible check-in & check-out time with baggage deposit service.
Bed & breakfast : buffet breakfast with all the basic elements needed and with long serving hours (6h30-11h, and to 12h on weekend).
My room was with window to the mini-courtyard side so very calm (also thanks to the other guests that didn't make much noice).
The cleaning lady cleaned the room everyday and added products needed.
DISADVANTAGES
The room is a little bit old in terms of walls, furniture but was overall clean. The wood floor could be a source of noice. The matress was kind of soft and bounced a bit...
There wasn't any photo on the Airbnb page when I booked the room so I didn't really know what to expect.
