My girlfriend and I stayed at Viola's flat for about a week and we were really impressed with it. The apartement is very clean, cosy and decorated with style and taste. There is everything you need and even more. The location is great - very close to the metro, few stops away from the center, 15 minutes walking from the Central station, big supermarket in the neighborhood and any kind of stores.
Viola was great hostesse, the communcation and the checking in/out went without any problems. She was very welcoming and left at our disposal many maps, tips and notes that helped us a lot with our journey in Milano.
I definately recommend the flat!
