We regretted staying at this place. It was very small, even for two people. There's nowhere comfortable to sit and relax except the bed. Everything feels cheap and worn. It was annoying having to enter 4 different door codes to get in every time. The spiral stairs to get up to the loft were so tiny and steep it felt dangerous (especially if you're half asleep). The upstairs loft was so short I could not stand up straight.
The location was pretty good. Short walk to fun touristy areas nearby. There are a few good restaurants we found right nearby - Kintaro Cafe was good for breakfast, Corner Cafe was excellent any time, and L'entent around the corner had a good dinner (especially the sticky toffee pudding!).
The host was communicative and seemed helpful, but we didn't really interact much. Check-in was smooth even though it felt complicated at first to figure out all the door codes. The elevator is tiny and took multiple trips to get our luggage up.
Overall, I wish we had stayed at the other place we were at in Paris and just visited this part of town once or twice.
