Location is absolutely fantastic, literally just 1 minute away from Piazza Duomo. Even though that area is noisy, the 4th floor apartment has double glazed windows, ensuring that there was very little noise within the apartment itself.
The apartment was clean, and check in process was very easy. For people who need to leave their luggage, the restaurant just outside the apartment has a "leave baggage" service through the "stasher" app. Very convenient.
Highly recommended and we will deifnitely stay there again when we are back in Milan.
