We came to Vienna by bicycles and so we were not sure at what hour we would come. Roberto left the key in the nearby restaurant so we were relaxed about our arrival time. The communication with him was smooth and helpful. The apartment was very clean, well equipped and there were even basic things in the refrigerator and kitchen. We were able to store our bikes in the separate storage for bicycles which is available in the building. It was a very good experience and we can only recommend this apartment to any couple.
