There is much to like about this listing. The location in the Latin Quarter is lively and fun, with the flat well enough back off the street to be quiet at night. The living arrangements were as described- it is a long flight of stairs up. It is not air conditioned but Nadia provided two fans that helped us survive the +90 degree heat. The flat itself was well suited for us- mom traveling with young adult son. It's pretty small and with no privacy for the bedroom with loft, which wasn't a problem for us.
I wouldn't recommend this listing for more than three people (a couple + with a third who is game for sleeping in the loft). Even though the couch pulls out in the living room, it would be a tight fit when it is out and people would have to climb over it to get to the bathroom. It's also not great for people who want to cook a lot at the flat. The tiny kitchen is okay and is stocked with some basics (e.g., salt & pepper, olive oil, tea & coffee), but the oven and dishwasher do not work and there's really not enough dishes or flatware for more than 3-4 people with almost no serving dishes. Again, not a problem for us but could have been if we'd wanted to eat in more. Overall we were happy as it worked very well for us.
