I stayed at Yves apartment for four nights for a prolongued weekend. The Location of the apartment is great, which I knew beforehand and which is why I picked it. The Check-In itself went so-so, I had to wait 20 Minutes in front of the apartment, even though we were supposed to meet at a certain time. Yvens was nice and helpful.
The Apartment itself is very very low budget, the tiles in the bathroom are falling down or are missing completely, the curtains are falling down as well, kitchen is not at all equipped to cook anything. You have a microwave (pluspoint) but except for one large pot nothing else.
The apartment is really not in a good state, of course it is old (like all Parisian buildings), but there is a difference between old and well kept, and old and not well kept.
The big bed was very comfortable though, quite a firm mattress, which I appreciate.
All in all the stay was ok, mainly because of the great location, but the apartment itself is far from comfort.
