All in all, nice apartment in a quiet place. about 40 min walk to the downtown, walking distance to all shops, bulangeries, patisseries, etc. No noise, clean apartment, well equipped. One of the bedrooms apparently was converted from the dining room, so the isolation from the living room is very weak (glass door with curtains).
A few details about the location: number of shops on St Denis is closed (covid?) and the street itself is sort of dirty with debris around but this can't be held against the rental place. Subway and buses are a minute away. good value overall and no regrets :)
