I had a nice stay in the apartment which I rented by myself for 4 months while studying.
Michael was a very helpful host. There was a couple of issues during my stay, but Michael was helpful and replied to my messages quickly. It is worth mentioning that the apartment is on the 5th floor without an elevator so you’ll get your daily work out when walking up the stairs. If you are taller than 190 cm the shower is also a bit too low (although it is doable, but you can’t stand straight).
I would say that the apartment suits well when you rent alone, maybe also for couples staying in Milano short term.
