We stayed at the Airbnb for almost three weeks. It was our first time in Paris and we were very happy to see that the apartment was in a very good position. The place is in a very nice neighborhood with restaurants, cafes, close to public transportation and even to a school. The communication with the host was impeccable and it started even before arriving to Paris. We arrived after the check-in time but the host welcomed us and was very kind to help us with our luggages. The fact that the apartment was at the fourth floor without an elevator was not a problem at all objectively. Therefore, if you are considering to stay at this Airbnb but are doubting about the elevator factor, I think that you should not let yourself be conditioned by it. The apartment was perfect for two people and really cozy. Considering that we stayed for almost three weeks we really felt like home. We also received a cleaning service for free in the middle of our stay which was very helpful considering that we stayed in Paris for study/holiday reasons therefore we were quite busy. At the end of the stay the host helped again with the luggages.
Overall, there are no negative remarks. We just suggest to bring your own towels, sheets if you are staying for many weeks as we did.
