Apartment is at a very good location - up to 10 minutes walking to the metro line 1 which goes through the center of Paris. There are all kind of shops close by. Cozy quiet yard, no noise from the street at all.
Wifi is very strong. Kitchen is equipped with all necessary stuff. Linens are provided. Beds (double bed and sofa bed) were comfortable.
Pauline and her boyfriend were really nice, reliable and pleasant people in general. They were always accessible by phone. Also, they were kind to let us check in late at night.
Photos and information in the description is a little bit outdated. It was no problem for us but for some people it might have a difference - there's no bath, just a shower; living room is not so spacious since there is more furniture; TV was not working (it might be temporary).
Also, important note - there are no doors between the bathroom and the rest of the apartment (toilet is separate from the bathroom) so be aware of that. You can think of "kind of" temporary doors solutions but it's not the same as a private space.
To sum up, stay at Pauline's place was a good experience with a good value! Perfect for a couple, also good for 3 people.
