Had a great stay. Luisa was a great host--informative, friendly and straight-talking--we really liked her; the apartment was beautifully located and bigger than I imagined. It's on the fourth floor but there are lifts. Walking distance to most of what you want to see in Milan. There's also a good little supermarket right next door and parking lots 5 to 7 minutes away. Be warned--Milan parking is pricey at 25 to 35 Euros a day.
Two large rooms with good windows and roller shutters to keep out both light and noise. The large bed in the bedroom is vast but a bit hard--we slept well though. Our lad seemed comfortable on a trundle bed in the sitting room.
The kitchen is a little tight but we managed to prepare food in there okay. It would be nice to have some tea bags and sachets of UHT milk, but that seems to be rare in European accomodation.
Overall, this is a great apartment in a great location in a lovely city. Highly recommended.
