Marilena's apartment was supplied with everything we needed, including comfortable bed, lots of room to spread out, good wifi connection, great shower with rain shower head and lots of hot water, and well-stocked kitchen.
The apartment is lovely and in a perfect location. Go left on the main street outside the apartment and it's a short walk to the Duomo. Turn to the right and it's an easy walk to a full-service grocery store. The walk to Santa Maria delle Grazie to see the Last Supper was about .7 miles away. The apartment was stocked with local maps and tour books (Rick Steves for one) to help you plan out your visit.
There's a tram stop a few steps away and a subway station near the duomo.
Marilena was very responsive. From the US, when I sent her a query, she always responded by the next morning. Once in Italy, in the apartment, her response time was typically just a few minutes.
There is noise from the sports bar across the street, so if you're a light sleeper, this might bother you some. For the first 3 nights we stayed there, it typically quieted down by 11pm, but our last night was a Friday and there was still some noise coming from the bar after 2am.
All and all, you couldn't ask for a better apartment in a great location with a wonderful hostess.
