Politecnico di Milano is one of the most important and famous Engineering, Design and Architecture univerisites in Italy and Europe.
All of the faculties are very complete and give all the skills (and some more) you will need in the field you are studying.
The professors are skilled and valid: most of them are researchers and have lots of publications; despite this, they are usually very helpful and available toward the student and his necessities/problems/doubts.
The studies inside the Politecnico are not easy and sometimes seem as impossible, but at the end they are very rewarding and give you an “easy” access in the “job world”.
If I could choose again which university to go to, I would choose again the Politecnico.
