I needed a place to work remotely, enjoy the city, and rest. This is a great apartment and location for anyone looking to do just that.
Work: the building itself is quiet, internet speeds are great, and street noise is minimal (you are central in a major city, so any location would have some noise, depending on your working hours). Multiple cafes and co-working offices are a short distance away, if you need a change of scenery.
Vacation: Quite centrally located, I never felt worried about how long it would take to get to and from tourist sites in Paris' central neighbourhoods. The neighbourhood itself is very active, from restaurants and cafes to shops. The area is well lit and safe: I saw many solo women locals and travellers walking around the neighbourhood late in the evenings.
Rest: The biggest downside is that the apparently newly remodelled bathroom is quite small: the sink is tiny and awkward to reach. The bathroom itself was very clean, probably better than hotel quality. It was easy to rest here, even during +30 C heat, with good air conditioning, a comfortable bed, and a quiet building at night.
