Angelo was unable to attend as we arrived so his assistant, Sisira, called as we were catching a cab at the Termini to make sure our train arrived on time and that we would be at the apartment as expected. Sisira met us at the door and helped with our bags - fortunately, as the elevator was being replaced and was out of service for the duration of our stay. Angelo had kindly provided various foods and drinks and Sisira made sure we knew how to operate all the electronics - washer, dryer, dishwasher, TV, heating, etc.
Ambrosiana is a fantastic location for the Milan Duomo and Galleria. Even Castello Sforzesco is only a short walk (about 15-20 minutes if you can avoid the shops and worth the visit). You also need to go to Via Mozart 10 (Villa Necchi Campiglio) and sit in the garden for an afternoon drink and a tour of the villa and 10 Corso Como for a bohemian experience of art, literature, food and drink and the "hidden" rooftop garden.
Highly recommended restaurants; SlowSud Cuchina di Strada (literally around the corner and absolutely superb), Cafe de Ville on Via Dante, and Pizza Caputo on Via Facone for the best Calzone.
