Nice stay at this apartment. Great location, good communication, the apartment was clean, and the shower was really great (perfect water pressure, drainage, clean, dual shower heads with one being a waterfall style). We loved that there was a living room, and a closet to hang our clothes. We loved that there was a Velib station right outside because we used bicycles to get everywhere. Wi-fi worked well!
Potential guests should know: the elevator is tiny - it's a triangle shaped elevator and the triangle is half the size of a very small square - a single person and a large piece of luggage may not fit. My husband and I could only use it together if we were standing pressed against one another.
The apartment was hot at night even with windows open and there was not a fan - a floor fan would make a big difference. There were only two pillows on the bed - two extra in the closet but no extra pillow cases for them and no extra linens at all in the apartment. We were offered two extra pillow cases for a fee. To get and return the key you have to go to a shop that is about a 10 minute walk from the apartment. Our flight was leaving early in the morning before the shop opened and we were allowed to leave the key in the apartment instead, which was much better.
Overall had a great stay, but these are some details we were surprised by, some of which seem like could be a very easy fix to make the guest experience a lot better.
