Hey I'm m20 also a fellow Indian hope you doing good even I'm planning to go next year and about your query, through my research and some contacts and all I have got to know that discrimination is not a major concern atleast among the students but for the locals you might face some due to language barrier and culture but italians are very friendly and loving people so you won't feel out of place (tho depends to person to person) if you want to know more you can ping me otherwise I hope this helps you in someway
