I did not get to meet Mario himself, but was greeted by one of his friends who was most helpful in giving advice on local restaurants and places to visit. The apartment itself was very clean and well equipped. It is a bit small, but cosy, with a superb view of the city (well worth the climb of four flights of stairs) ! The apartment is in a great central location! Very close to the main train station. No problems with my stay. I would highly recommend this studio apartment.
