PROS:
* Great placement if you are attending a Bercy event - it's just 4 minutes on foot, absolutely perfect. It's also very close to the métro.
* Well furnished - this is someone's actual apartment and so the equipment in the kitchen reflects that. It's got everything you need. It's got a full size fridge/freezer (not common for Paris studios)
* Confortable bedding and bathroom
* Good checkin experience and pretty quick response from owner for any questions
CONS:
* Door lock is only a latch. There is the remnants of a full lock but something must have happened to it and so you can not lock the door, it's just secured via the latch when you pull the door closed. Kind of unnerving when you leave your laptop and valuables.
* Unreliable internet - less than 10MB downloads (pretty low for Paris) and pretty unstable even after restarting the box. Had to use my 4G (which thankfully is above 100MB in the apartment).
* Very thin wall. There were constructions in a nearby unit and it was pretty loud during the weekdays. There were also some very noisy families constantly screaming (both the kids and parents!) during the first few days. The good thing is that there is no street noise (since it's facing a parking lot) so make sure you take your ear plugs (always a suggestion when renting anything in Paris).
