my first time in milano!

hello everyone! in june, it will be my friend's and i first time in milano. we're coming all the way from argentina!!

what places should we visit? everyone keeps telling us to go to the duomo rooftops, da vinci's "the last supper", and the upscale galleria vittorio emanuele II. but i know there's so much more being gatekept lmao

also, we wanted to know if the place we're staying it's safe. i understand that via mario fusetti & via filippo argelati is a nice place during the day but we were thinking about going out to clubs and etc. if you think it's unsafe, any advice or recommendations for places to stay? we can still cancel the reservation. thank you all and sorry for my bad english 😭😭 i'm trying my best here 🙏
