I didn't get the chance to meet Marina as she wasn't at home for the 3 nights I stayed at her place, but my friend and I were greeted by a very nice friend of hers and she left a handwritten note with some recommendations on where to eat and what to see in Milan.
The neighbourhood was conveniently located, you have a out 30min to the city centre, plenty of public transport (tram, bus, metro) nearby and a shop right across the street where you could buy your public transport card. The place was clean and had everything one could ask for (there's no oven in the kitchen, she has a microwave, though). All in all, I would recommend staying here.
