Pasquale, a friend of Sergio's, contacted me before I arrived in Milan, directing me to the easiest way to arrive at the apartment. He was sweet and helpful. The apartment is centrally located minutes from the Duomo and shopping and restaurants.
The apartment is on the 5th floor, but the building does have a small elevator that goes to the 4th floor. The apartment was small, well appointed; the kitchenette was stocked with biscuits and supplies for tea and coffee. There were toiletries in the bathroom and the bed was comfy.
