Apartment is beautiful (well decorated, bright during the day and nice ambiance) and the location is unbeatable. You really get the cool, local vibe staying in this apartment and neighborhood.
However, as the other reviews have mentioned, the 5 floor climb can be a bit of a challenge - particularly with a big heavy suitcase. Furthermore, the apartment is pretty dim at night which can make it a little challenging to navigate the apartment at times. I did encounter an issue with turning on the shower - which the dimness of the apartment did not help the situation. Sandrine, however, was incredibly responsive - responding back quickly and at all times of the day. While we eventually resolved the shower confusion, I do think this could have been mitigated with better instructions.
All in all, it was a nice apartment but it was not the easiest apartment to navigate.
