This place was great for our family of four adults, making creative use of a lot of vertical space to create little nooks where everyone could hang out without feeling like we were on top of each other all the time. Pablo was a great host, meeting us at check-in and offering suggestions for local places to eat. The apartment stayed fairly cool on all but the hottest days even without air conditioning, so the fans in each bedroom were enough to keep us comfortable. We also had a lot of fun opening the massive skylights to let the hot air vent out every evening.
The location is convenient to restaurants, boulangeries, and several metro stops and the private gated alley is safe and quiet. The neighbors were friendly, too, even though I'm sure they see a parade of tourists coming through all the time. I recommend this as a great base of operations where you can live next to real Parisians and have enough space for everyone to find their own spot.
