Staying at Simone and his roommate place was awesome! They both are very nice and welcomy, always willing to give advices and help. It was also super easy to communicate with them as Simone always answered my question very fast.
The flat is ideally localized right next to the Navigli (cool area to hang out) and all commodities.
So if you go to Milano, definitely go there! I would come back without a doubt :)
