This place was perfect for my boyfriend and two friends! It was very clean, modern, and cute. The little deck was cute as well. The key situation was a tiny bit confusing but follow the directions and you should be ok!
You could definitely fit someone on the pull out couch but probably would want to close it up during the day if you're spending time there. Location was great, we were able to walk to everything including the restaurants at the end of the street for a nightcap. Because it is on a side street and in a basically standalone building, it was pretty quiet aside from minimal traffic.
We all were provided towels, there was a washer, hair dryer and some toiletries.
I would definitely rent here again if I go back to Paris!
