This place is kinda just okay, with the potential to be great. It's as if the owner put a bunch of care and effort into setting up this Airbnb to begin with, but then has not kept up with it at all.
As others have noted, the flat is wonderfully located and has been decorated very nicely. It was very quiet (except for occasional neighbor noise / thin walls) and was priced nicely for the location.
Here's a list of the not-so-great things that outweigh the nice things. What I find most disappointing is that this review is not the first to mention many of these issues, which suggests that the host isn't interested in improving.
-The flat smells like sewage water. It comes from the shower drain, especially when the shower hasn't been used for a while. It was very apparent when first entering the flat after being out. We bought candles and burned them the whole time we were there.
-The bathroom sink drained slowly, filling with water any time you used it.
-The bathroom and bedroom doors are missing door handle hardware. There are multiple light switches broken off throughout the flat. All of the doors need some WD-40 and creek so loudly when moved that I swear it must've woken the whole building.
-There are two televisions, neither of which are hooked up to anything other than power. What's the point?
-The bed is incredibly firm and the pillows flat. Personally, I preferred the bed to the normal European bed that is too soft with no support, but my wife slept poorly the whole trip. It was not much softer than had we slept on the floor.
-One of the radiators in the main room doesn't turn on, so that room is cold.
-The washing machine is broken. FYI - there is no dryer.
-There's no table area to sit at for eating/relaxing. The only seating options are two floating chairs and the couch.
-The decorative light-up dog art that you see in the main cover photo isn't plugged in, or easy to plug in without moving furniture. So don't count on using that.
-We stayed in the flat for 9 days, but there was only 1 trash bag and 1 roll of toilet paper. We had to go out and buy these ourselves.
-The images make the place look bigger than it is. It's very very small. We were only two people, so it was fine, but I would not recommend having any more than 2 people stay here.
-The listing makes it look like the windows face out to Saint Michel, but they don't. They face into the courtyard with nothing to look at. The flat is quite dark without much lighting.
-The host did not provide any instructions (other than entry and wifi) or welcome booklet like many Airbnb's do. As an American visiting Europe, simple things like turning on radiators or using the Ikea microwave/hotplate aren't straightforward. I had to Google to find user manuals to figure out how to operate the kitchen light, exhaust fan, microwave, radiators, and washing machine. We didn't know where to take our trash bags, so they just accumulated. It would be much easier to just have a welcome guide, wouldn't it?
I mentioned a number of these things to the host during the stay and, though I did receive responses, there didn't seem to be much interest in solving any of these issues while we were there.
Overall, we still had a wonderful vacation to Paris and were not deterred by the flat. The place wasn't so bad that we felt that we needed to leave and go elsewhere. But I really would have liked to see a bit more effort from this host, and less of my own time spent buying toilet paper and candles and Googling microwave user manuals.
I would come back to this flat if these issues were addressed, but I don't have much hope that they will be. I'd suggest you look elsewhere.
