The apartment is quite charming and has a good feel to it. It is also very small, smaller than the photos would suggest. (Very large people should look elsewhere.) But Paris is a city of charming, tiny places. The apartment is well equipped with everything one might need, and there are plenty of shops, markets, restaurants and cafes close by. This is postcard Paris.
The metro is a block away, and many destinations are walkable. There are plenty of buses as well.
We did not meet Olivia but her friend checked us in and was on hand should we need anything.
One small thing could be better: The photos show attractive window boxes with flowering plants. However what is there now are just ugly, dead, yellow plants - a bit sad. Better not to have anything there at all.
Altogether I would recommend this apartment.
