This was our very first experience with an Airbnb.
Location is fantastic, right in the middle of the Latin Quarter. You do get hounded by restauranteurs as you're walking down the street but by the end of the second day they finally gave up on begging us to come into their establishment. With that being said, the restaurants that are close by are very good. The entrance to the metro is right around the corner. The street is walking only so for taxi pickup and drop off, you'll have a little bit of a walk. The apartment is far back from the street so it's very quiet.
Communication was fast, check in was easy, and the apartment has most of the amenities you would need. The only thing I would suggest is adding some instructions for the heating in the living room and bathroom. It got really hot and there are no windows except for two in the ceiling that open by remote (only one worked). I originally booked this for our family of four because of the location and it said there was a washing machine in the apartment or in the building. There wasn't that we saw. That was disappointing. The water pressure in the shower is awesome but the ceiling is VERY low. I'm almost 6' tall and had a hard time washing my hair standing straight up.
There is one bed upstairs in the very low-ceiling loft space and it is a very hard mattress. The rest of the sleeping arrangements are downstairs: a couch and a single chair-like thing that looked like it was supposed to fold out into a usable single bed but it was either missing a cushion or we just couldn't figure that out either. There is also a table and chairs for extra seating.
We really liked this space, but it just didn't work for my family. We ended up leaving a night early and spending it in a hotel. I wouldn't recommend it for anyone with mobility issues. There is a pretty big step down to enter the apartment, one big step to get in and out of the shower, and the stairs to the loft are steep and narrow (which is mentioned in the listing I believe). It would be great for a couple, three people max in my opinion.
