Elisabetta and her son Philippo were the best. They gave me very helpful information and treated me like I was part of their family. The place is very clean and the room was spacious. I was quite comfortable there. The bus ride (either 11 or 17 from Bronzette stop, which is right in front of their place) to San Marco is about 15 minutes. From San Marco you simply walk down southward towards Duomo, which is another 15-20 minute pleasant walk through a maze of streets and charming restaurant rows.
