During a vacation - about my accommodation :
"Must to have" things: Secure, clean, good located
"Nice to have" things: Comfortable, cozy - like having a spirit with the decoration.
Susanna's flat are suitable in terms of both. Good located, secure, clean, comfortable & wonderful balcony. She is also ready when you need more info / help for sth.
I recommend this flat to anyone who looks for a place in Milan.
