We stayed 2 weeks in the apartment, and overall were very happy with it.
It is well equipped, although an actual coffee maker would be nice instead of a pod machine. We were able to cook full meals with no trouble.
Clothing storage is at a premium, but we pack very light so not a problem. The bed is firm and comfortable, the couch and coffee table could do with an update.
There are lots of outlets, including by the bed so charging devices is easy
Some things to note:
There are 54 steps and no lift to reach the apartment. The shower entrance is only about 16" (40cm) wide.
The toilet is right off the living room by the kitchen, so you have a bit of a walk when you get up in the night.
The location is excellent, we were able to walk almost everywhere and we are in the 65-75 yrs age.
There are plenty of restaurants within a 5-10min walk (Rue des Marronniers and Rue Merciere) and lots of shopping.
We would certainly recommend this apt for either short or longer stays.
