Me and my girlfriend stayed 1 night at Cristiana's place. The room and the house was good, clean and there is everything you need in the kitchen. Cristiana was a great host.
It says just room but it was like the whole house. We didn't met her face to face but she was very helpful and responded very quickly. The place is not in the very center of Milan but it takes 10 minutes to reach overground metro station and also it takes max. 10 min to Milan center. Also you can find maps and useful information inside the house. If you have car there is a free parking place right across the street and it's safe.
We recommend this place.
