Jean-Christophe helped me carry my suitcase up so the stairs weren’t so bad on the way up, you get used to them pretty quickly. The flat can be noisy with other people around as the walls are thin, but that wasn’t a problem staying during COVID times as it is less busy. Fantastic view, and ideally situated with lots of shops nearby and a lovely nearby park as well as three metros close by and only a half an hour walk to the Louvre. Would very much recommend for one person staying in central Paris.
