The apartment is big and spacious, the bed comfortable and the kitchen with the necessary basics. Although it does need some maintenance in general, as well as a small upgrade in their curtains. The location is good, as long as you go in the direction of the Louvre, the opposite direction can feel a lot less safe.
The building is old, so you can hear everytime someone opens their front door or uses the stairs.
We had an issue where we were informed in less than an an hour that an internet provider would come to the apartment, a message we didn't read since we were out, despite them knowing the date and time two months in advance. We found out when we arrived to the apartment to find the door open, and inside another employee of the hosts we had not met beforehand, with the internet provider, all our belongings out in the open as we had left them since we were not expecting anyone to come during our stay. It was not at all a pleasant experience, even with them apologizing, we did not feel as comfortable.
