Giulia is a very nice and careful host, she took care of everything we needed and always reacted very fast. The location is wonderful. A tiny cozy apartment in the middle of the best side of the Navigli life, but hidden in a very quite court. Less than 5 minutes walk (if you walk slow, but if you walk like a Milanese, it's 3min) from the Metro station of Porta Genova (green line, you can reach almost every place in about 10 minutes). And a Garage for my car was available as well, not directly beside the apartment because the area is car free - but anyway very close, beside the Darsena (5 min walk from home). If you have a car, you should consider this as an absolute plus since the parking lots are expensive in Milan and it's almost impossible to park on the street as most of the areas are restricted to residents only.
We had a great time there, we'll use the same location if possible for our next trip to Milan.
