Good location in central part of Paris, near the Louvre. Relatively large apartment for just sleeping two in this area. Had issues with the shower drain running very slowly, and while the hosts were responsive the turn around time was long enough that we never got it resolved, despite a 5 night stay, and the hosts seemed to either not understand the problem or make some pretty extreme suggestions (turn off the water for the whole unit, etc) which we had to talk them out of.
Checkin and checkout were several blocks from the unit, which was a bit of a pain with our bags
The whole experience, combined with the lack of Wi-Fi and air conditioning (as listed) made me feel like I would not recommend a stay here.
