Donato's place is a cute Airbnb that is well located in central Milan! It's only a quick walk to the Duomo and next to a subway station. A different review mentions that a church bell goes off - yes, it does go off on Sundays, and it's right next to the Airbnb, but it's doable for sleeping. Donato was speedy in responding to all of my messages.
Just as an FYI, there is a fee for checking in after certain hours. The staff is amicable when letting you in and quick to arrive. If you're looking for an Airbnb that you won't spend much time in while you enjoy the beautiful city of Milan then this is for you!
