Hariesha,
IED Masters in ID is all in English. Domus Master in ID is in English for 2 months and then all in Italian after that. So, if you are not fluent in Italian or no Italian at all, IED is a better investment than Domus. Simply because you will understand the lectures better. IED also offers a 3 month internship after. Domus is too expensive also. I have checked out IED school and it is really nice and up to date and clean and full of really good looking people! The staff is really friendly. It is close to the centre and the famous fashion and cultural streets of Milan.
As for the rest, I have no clue!!!
Good luck!
