We are a family of 4 (2 adults, 2 kids ages 10 and 11) that stayed for 1 night at Mariella's lovely apartment in Milan. It is a great spot, fully renovated and very modern, clean and well designed. It is exactly as shown in the pictures, and our whole family loved it.
Communication with Mariella was clear, accurate and timely. She was very helpful in providing information and maps, and seemed to genuinely be interested in ensuring we had a great visit in Milan. The apartment is about a 15-20 minute walk from Duomo, which was ideal. At the time of our arrival (10pm) street parking seemed to be limited, so we chose the parking garage Mariella suggested which was just around the corner, 25 Euros for 1 day. We were able to keep the keys (rather than leaving them for the car to be moved), which is our preference.
All in all, a lovely spot that we would definitely recommend to others!
