I'll start by saying that although there may be some negative parts to the apartment the pros far outweigh the cons of this lovely home!
Pros: The location is fabulous! Its steps from the metro, there is a delicious bakery called Joël's right around the corner, the Korean restaurant (Doran Doran) is directly across the street and so good. Grocery store is a 2 minute walk as well. Its really great. The space is huge for a Parisian apartment and the beds are comfy enough. We felt very safe in this neighborhood as well.
Cons: The home has a musty smell but if you keep the fans and air on then its not bad. Also the seating is limited but I spent most of my time exploring Paris anyways. I'm really only writting these so you know what to expect but I really don't find these things that big of an issue.
All in all I will definitely be back.
