We stayed 2 nights at Valentina's apartment and we absolutely loved it! Unfortunately we couldn't meet her personally - the mate met us at the place, but she was on the text all the time giving me instructions and tips for our stay. The apartment itself is small, but very pleasant and comfortable for 3 people. Location is also very convenient since it is on a main street with public transport just outside the door. Also is very quiet, since it is into a closed yard complex. The only downside is the parking, but you can park across the street under the treeline that separates the main street from the local one. Also watch out your step when you go close to the main bed in the bedroom, because there is very little space between the bed frame and the drawer and you can easily hit your leg - did it two times and my wife 3 :-)
Overall very nice place and absolutely helpful hostess. I strongly recommend it to anyone who wants to visit Milan and blend into the local population
