I would highly reccommend Lorenza´s accomodation. Lorenza and her dog Luna welcomed me very warmly. It didnt feel like staying in one of those hostels or hotels but more like staying in with a close friend chatting about anything. I had access to the TV and got breakfast every morning. Everything was clean and tidy. Moreover, the location is really central.Everything can be reached by walking (for example Duomo, Castello sforzesco, Arco della pace and all the diverse restaurants). I will definitely come back to visit her and Luna :D
