A very comfortable apartment and a very nice owner. Daniela's apartment is located right off Corso Sempione, which is a nice area itself, it is also very close to the main attractions: Castello Sforzesco is about 15-20 minutes walk through a pleasant park, Duomo can be reached on foot in half hour. There are good transportation links as well. The neighbourghood has everything nearby: good restaurants, supermarket and even some interesting shopping (a couple of traditional artisan shops on Canonica street).
Do believe Daniela's suggestions about things to do and eat (her restaurant suggestion was excellent)!
The apartment itself is very well ewuipped with everything one may need (including an iron for your frocks if you are heading to La Scala), the view from the terrace is also good.
If you can book this particular apartment do not think twice: highly recommended!
