First thing's first, the apartment is beautiful and the location is great. The view is immaculate. With that said, there were so many inconveniences throughout my stay that make it difficult to recommend to anyone.
The biggest issue that I have is the fact that there's is a cleaning person that goes in to the apartment whenever he feels like it. He stays there for extremely long periods of time. In one instance, he stayed in the unit for over 6 hours. In another instance, he came at midnight. One morning, I noticed him trying to open the door to my room without knocking or announcing that he was coming in. It made me feel extremely unsafe.
Secondly, there were so many inaccuracies with the listing. When I booked, it said there was air conditioning. There was not. I contacted the owner about this and he immediately changed the listing to remove the AC. It was misleading. It was scorching hot in the apartment at times to the point where I could not sleep.
Next, the Internet is terrible. Forget about getting functional connection here. I work online, and I had so many issues trying to work from the unit, that I had to leave to a nearby hotel to get working internet.
Another huge issue is the fact that they do not allow any type of guests over. Even if they're not staying there, they do not allow you to bring anyone into the unit. This was such a huge inconvenience, especially considering that the cleaning person would harass me and the other people staying in the apartment about it, even when there was no one there. If he suspected there might be someone else, he would look through the bathrooms, the kitchen, and other rooms to look for "clues" of guests being in the apartment.
Honestly, this whole experience soured my stay in Paris. If you're thinking about staying here, it's not worth it. I would look for a different listing or even book a hotel.
