PROS:
Great, central location near restaurants, cafes, shopping, Notre Dame, Latin Quarter, etc. The apartment was as charming looking as its photographs, if a bit smaller in person, which wasn't an issue for us (party of 5) -It's still quite a large space for Paris.
CONS:
Upon arrival, there was a filthy mattress propped up against the front entry which I'm sure was no one's fault, but it looked pretty darn sketchy nonetheless. The woman who let us into the apartment could not figure out how to get the lights on for some time, but figured it out eventually. Incidentally, every other bulb in the apartment flickers, so if you have any sensitivity to this, be aware. We opted not to get the €30 "cleaning kit" (whatever that is) but we were still surprised that they only provided one garbage bag for 5 people x 5 nights (the one already in the bin), and zero other cleaning products, meaning if we wanted to do laundry or wash any dishes we'd have to buy way more than we needed from the market -which we ended up doing. It just felt a bit scammy to have to buy the essentials that are usually automatic for an Airbnb. Needless to say, this also extended to cleaning supplies or soap of any kind. The bill kept growing. There were also no napkins, no paper towels, no cooking supplies like salt and pepper or oil, no sugar, no shampoo etc. etc. I can only imagine the surplus of these items that previous guests have left behind. Point is, read the fine print which basically outlines that they supply nothing and will charge you for any perceived extras.
Our bathroom's rain shower head had no water coming out of it, rather the water spewed across the bathroom ceiling only to fall the the bathroom floor about a foot away. Additionally, there was quite a bit of what appeared to be black mold around the shower head. Our bathroom sink leaked onto the floor beneath every time we used it. It was apparent some hasty work had been done to remedy this as there were giant globs of caulking all around the drain pipe. Concerned that this would case a leak through to the first floor, we immediately contacted Guillaume who said a guy would come out that day. No one came. That's the last I heard from Guillaume who had previously been attentive and prompt in his responses. The following day, a guy did come to "fix" the sink, but 3 hours after he left the leak was back at full force.
