We had a wonderful Milan weekend at Jannu's place. It is a spacious loft in a pretty, quiet and secure courtyard, close to Navigli, with all its bars and restaurants, and not far from Romolo station.
The apartment complex itself is VERY cool - industrial converted to apartments. It has a great atmosphere and friendly neighbors.
The apartment was clean and well equipped, and we felt very much at home. Communication with Jannu was quick and easy.
Highly recommended!
(One note: In the apartment, there's a staircase leading to the upper floor which may not be suitable for young children)
