Overall - Very clean, beds were comfortable, communication was quick and helpful, location was great!
Easy tram ride (download the ATM app for tickets) to the Duomo and beyond, plus a ton of cool things in the neighborhood within walking distance.
The neighborhood is very cool, especially if you're looking for a less-touristy area. There are lots of cool shops along the street the flat is on. Discovered Betto across the street, really charming manager/staff, great wine, and fantastic cannolis!
Flat has most things you will need, but if you plan on doing any sort of extensive cooking, you may need to get some things for your self. Luckily, there is a small market nearby.
Beatrice was very quick and helpful with communication, and offered us many recommendations for things nearby. She was also on hand for any questions or concerns we had during our stay. She even arranged for someone to let me in one night that I was separate from my traveling companion and did not have the key to get in! Very thoughtful and attentive host.
Overall, we loved our stay and would definitely stay again if we visit Milan in the future!
