Valentina's place is just perfect! We stayed at her brand new studio for 4 nights during our summer trip in Milano and everything was perfect! The studio has a nice size for a 2 people stay and is really convenient. The apartment is exactly as described on Airbnb. The situation is really convenient cause it just next to the Garibaldi FS Station which is straight to Malpensa Airport and Stazione Centrale as well, easy access to the Duomo (15min). The district is quite nice as well and you have some really nice place to go for lunch or dinner. Valentina has written a tiny guide in which we found all the information we needed and she gives you really nice tips as well! Unfortunately we did not met Valentina but our stay at her place was just perfect for our 5 days in Milano.
I strongly recommend her place for these kind of staying.
