While the apartment is centrally located, for us it was not worth the location. We left after two nights and went to a hotel.
Overall, it is just a very uncomfortable, bare-bones room. The bed is extremely hard, it was impossible to sleep (we nicknamed it "the slab"). There is no sofa bed as the listing indicates. There are bugs in the bathroom, and the building is very noisy. We were given just two small pillows and two towels, and there were no amenities such as tea bags, a bottle of water in the fridge, etc.
Finally, it was extremely hot when we arrived, and the fan in the room did not work. We messaged the host about this and they responded that they would fix it. They did bring a replacement fan, but not until the following day.
Overall, this place is simply not a cozy or even semi-comfortable respite from a busy city like Paris.
