Our stay at JN's apartment was truly perfect! The apartment is super close to the Pantheon, and 7 minutes walking to get to Notre Dame and Jardins du Luxembourg, so the location could not be better. We were 3 couples staying there, and even the couple that slept on the living room enjoyed a very comfortable sofa-queen-bed. The apartment is just upstairs from some restaurants and bars so it can get a little noisy, but even that surprised us, because having the windows closed the noise was not loud at all. The check-in process was seamless, we arrived late at night and were able to get home with no issues. The only couple of things to bear in mind are: 1) the apartment is on the small side, so there is not a ton of room for at-home dining (because of covid we avoided eating out at night because you have to stay in such closed spaces so we had dinner at home for the 4 nights we were there and there always had to be two people sitting on the couch and the other 4 sitting on the kitchen stools), 2) the fridge is small and there is no oven per se, though we used the microwave in the oven setting and 3) the stairway up to the apartment can be a little hazardous, as the steps are small and narrow. Overall we had a wonderful stay at Cosy 2 and we would recommend to any group looking to stay in a great location in the center of Paris!
