BEWARE OF THE MOLD!! There was flooding, and while DD states he is working on the problem, he should have made me aware of the situation as I became ill after 5 days of sleeping in musty, dank air. The bed is very uncomfortable and small. I am only 5'4 and my limbs were poking thru the rails. I ended up sleeping ( or rather NOT) on the trundle on the moldy carpet. I did not want to waste my time in Paris dealing with AirBnB's horrible customer service and trying to find other lodging last minute.
The location is unbeatable and DD was great in communicating directions and checking me in. It is as cute as photos, but maybe smaller than it appears. You can't wash your face in tiny bathroom sink without getting the floor all wet. No hand towels or soap in "kitchen area".
Overall, he really should not be renting his studio when it is not safe to breath in there.
