Alberto was a great host, he provided us with everything we needed for our stay. However, as other guests have mentioned this is a first floor apartment with only one window for ventilation. There was construction going on during our stay which prevented us from opening the window so the apartment was very musky. To add to that there is a mold smell throughout the apartment from lack of proper ventilation. In addition, the hot water lasts for two short showers so we had to stagger our showers day and night between the four of us. None of this is the fault of the owner, he is a great host and the apartment is centrally located in Paris. Alberto responded quickly to all communication and even provided us with soaps and shampoo. If you are allergic or sensitive to mold I would recommend finding another place to stay.
