We did not meet Marco during our stay, but we met his father Sergio who was incredibly helpful. The apartment was a bit difficult for us to find via car, but Sergio went above and beyond to help us get into the private parking area with ease. He made great recommendations of what to see and where to go. The apartment is a very short walk to the duomo and other attractions. It was very clean and had everything we needed! The apartment was beautiful and even had a balcony.
