Andrea's place in the top floor of the building is absolutely beautiful - nice vintage decoration and a wraparound balcony with a stunning view. Everything is as advertised and they have a great book of local recommendations. Location is convenient to Sondrio metro station (yellow line).
The only thing to be aware of is that if you're sensitive to light and sound (light sleeper), you may have a little difficulty here, but for a one night stay everything was perfect.
