The location of the apartment is excellent. As mentioned in the description, many famous attractions are nearby. Moreover, metro stations are close, and there are a couple of nice cafes (with different cuisines) right on the street where the building is located. The neighborhood is pretty safe and peaceful. The apartment looks just like in the pictures!
Note that the apartment is on the 5th floor and there is no elevator. However, it wasn't a problem for us. Also, you'll have to get keys in a hotel near the apartment (9 min walk) before checking in. The process is pretty smooth though.
The one thing we found strange was that the owner's clothes and other belongings were in the apartment. For example, the bedroom wardrobe was full of different clothes. Also, there were only 2 towels for us. We found other towels in the apartment but they were not clean.
Overall, we liked Corentin's place and recommend it!
