At the arrival Marcos son gave us the keys and explained us how things work. Even the flat was small it was cosy, very nicely furnished and we felt at home immediately. The flat was very clean and exactely as shown on the pics. The Navigli Area is is really just around the corner, a fantastic place to be but also very crowded at weekends. (Make sure you have a reservation for dinner.)
Marco and his family have been very friendly and helpful. Thank you, it was a fantastic time in Milano!
