I want a cheapre place to stay

I am Yu Yonai from Japan. I like to be friendly with people so it is totally fine to share a room with somebody. Hopefully, roome mates do not smoke inside of the room and, sleep in the night and wake up in the morning. It is welcomed to go hung our with roommates but it is absolutely fine too if they want to keep privacy inside of them. I want to stay near Politecnico di Milano. I do not think I make romms dirty or messy so much. I do not refrain from cleaning constantly. I want to cook to recuce the living costs.
