Five-Star EXCELLENT!!!!!
First, Carlotta is a super nice host. She is responsible, warm and full of passion. She can give very good advices for the guests depends on their needs. Otherwise, her quickly responses can make you feel very good.
Second, the house is designed by Carlotta, therefore, it is special. Very good for small family (three persons). Tidy, good daylighting and complete house supplies (even the first-aid packet).
Third, good WiFi, good hot water pressure, good location (city center).
Overall, my Milan stay was better than my expectation because of Carlotta. My best Airbnb stay and the best host I have met even. Next time to Milan I must book this warm apartment. Highly recommended ;)
