The room is ample with independent entrance and bathroom. It has air conditioning. The neighborhood is close to the center and the Navigli area, definitely a good location from which to explore the city. The only disadvantage for some may be that there is a bar downstairs which can be a bit noisy at night but didn't bother us much.
Adriano and his wife kindly agreed to store our luggage in their own flat next door until the room was ready. Adriano also gave very good recommendations for authentic Italian restaurants nearby. There is a small fridge in the room which is however very loud, so we cannot recommend leaving it turned on at night. But Adriano kindly agreed to store our groceries in his own fridge. The night before our departure he even arranged for a taxi to pick us up the next morning as our flight was very early in the morning. Thanks again!
