Christina ia a fantastic host, in all terms. She was flexible- enabling us to stay on a day, she was expecting new guests- , she was informative- sharing all necessary info with us and last but not least communicating to us, if necessary and ahead of arrival and departure.
The apartment is located in a calm district of Milan, the line 5 metro is a nice 3 minute walk. Carefoour is a good 10 minute walk away, but there are some smaller stores nearby.
