Some pros of this place:
-The location is truly amazing. The Latin Quarter is my second-favorite place in Paris and Ile. St-Louis is my favorite and only a short five-minute walk away.
-All amenities are true as listed (included/excluded) and the place IS very clean
-The shower has solid pressure and is comfortably warm (although the rain shower feature does not function)
As for the cons:
-The high cleaning fee ($90) is not included in the listing cost, masking the true price per night. The fee is especially excessive considering how small the space is.
-The couch/bed, pillows and blanket are extremely uncomfortable and not suitable for sleeping on multiple days in a row
-The apartment door lock is very sticky and took us a solid 10 minutes on night 1 to finagle (pro tip: pull the door towards you then try to unlock the door, then push the door open)
-They are not kidding about the 20EUR late fee. There are no exceptions, no matter the circumstances or how close to the deadline you arrive
In conclusion: would recommend only if paying <$100 total/night (including taxes and fees) and only if staying <2 nights
