We just spent 4 weeks in the apartment and had a wonderful experience. The location is terrific.
10 to 12 minute walk to most of the museums, and the main train station, and only a little more to the University building where my wife was working for a month. Having the Carrefour, Supermarket downstairs turned out to be very convenient and it is open every day. The central Market is also not far and offers a huge variety of fresh fish, meat and local vegetables, as well as great eating upstairs.
Antonello is a most gracious and helpful host, and is truly concerned that his tenants have a good experience. The kitchen is well equipped, and having two bedrooms made it comfortable for us to have my relatives come to stay with us for a few days.
We highly recommend this apartment. The best we have ever enjoyed in our travels.
