There are many great things about this apt, including:
-great location, close to good restaurants and public transportation
-charming building and apt (my daughter especially loved it)
-highly communicative and helpful host
-basic toiletries already there, such as soap and shampoo, as well as coffee to start your day
-great guide to local restaurants, bakeries, etc.
-helpful extras, such as offer for free cleaning and/or laundry service during stay (we didn’t avail of them, but thought that was very nice)
The only challenge, that was made clear in the description though I didn’t pay attention when I booked, is that (like much of Paris) it didn’t have air conditioning and it was crazy hot during our stay (to be fair, abnormally hot for France as it was between 93-105). They kindly got an in room a/c unit for the living room, but that was the only cool room. The 2 other rooms on that floor were still warm, and the 4 other rooms on the floor above were hot.
I guess because few places have a/c in France it isn’t even a filter option, so you need to carefully read all the details until the end when booking something.
