Beautiful and cosy apartment with a perfect layout for a couple or small family. Apartment is on the 6th floor with a very small elevator (not big enough for a baby stroller). The building is quite noisy (you could hear the upstairs neighbor taking a shower), but it didn't bother us. The owner lives in the apartment so lots of personal stuff everywhere which gives it a cosy feel but might bother others. There was no shampoo in the bathroom.
Montmartre is on walking distance (20 minutes). For the rest we took Ubers into the center as we didn't feel comfortable with public transport due to Covid. Overall we had a good stay!
