I stayed in this apartment with three friends and had the most incredible stay here!
Let me start by saying that the apartment itself is beautiful: it's on the top floor of the building and therefore has a ton of natural light. It's also super spacious and the common area is really comfortable. The real gem of the apartment is the terrace. While narrow, it's quite long and is that perfect, special touch that'll help make your Parisian fantasy come true (obviously, this requires good weather).
The location couldn't be more ideal. It's in the heart of the Marais and walking distance to the best restaurants, bars, and shopping.
The apartment itself was super clean. It was the first time the host was renting it out, so the owners had a bit more stuff out in the open than I'm used to. That said, we were respectful of the space and this was not a problem for us at all. Only inconvenience was we didn't have enough towels and had to buy our own soap/shampoo.
Host was super easy to communicate with and even helped me recuperate a forgotten item in the Airbnb after we had checked-out.
Overall, highly recommend and would definitely want to stay here again!
