Nives was super friendly, helpful and considerate. The flat is bright, cozy and location is very comfortable, it's very easy to get to the center by subway. It's also near Central and Garibaldi railway station.
Also there everything that you may need just 10min walk from the apt - supermarkets, restaraunts, bars etc.
I definetly recommend staying at Nives's place if you're going to visit Milan, she's a great host :)
