I was a single-traveler, staying 3 nights in Milano, and I am very satisfied with Maria Adele's place! Paolo, the co-host was also very kind. The location is very good, Duomo is reachable by feet (25 min using very safe/large streets, I used to walk alone in the evening without any problems), and/or by metro 10 min from Duomo and/or Central Station-perfect! The place is very clean, very well equipped, it is really very nice, in a nice and safe building as well. Nearby is a Carrefour supermarket-open 24h.
I would definitely recommend it to everyone because next time I come to Milano, I will try to book it again!
All the best in 2020!
