We didn't really have any trouble at all, the apartment was extremely well-located, and very safe. Laura was willing to accommodate us at check in & check out according to our travel schedule. Small things that can make a big difference when you travel!
The location is simply wonderful. The Duomo, the fashion district, the castle are all within walking distance. Take a food tour of Brera and see how you can make the best use of the location.. Metro station Lanza was a few minutes away, and a taxi ride to Centrale station (with luggage) is about 15€.
Overall we were very extremely happy with the stay and would highly recommend it. The apartment is just right for two people; we were a family of three but we still managed quite well..
