I rented the appartement 203 for approximately 2 weeks. It is a pleasant appartment to live in, the neighborhood is very calm.
All train/metro stations are at about 10min on foot and there is a 7eleven at 50m which is very convenient.
Concerning the appartment itself I lived there alone so I had plenty of room to store stuff. However, if you plan on staying there at 4 people you will have to be traveling light (at least not with two full full size luggages each).
The kitchen is equipped for cooking simple things which can be useful.
The bedding is comfortable, cleaning products, bin bags and so on are provided.
I definitely recommend, for two people this appartment is perfect, over two people you'll have to be a bit organized ;)
