Alessandra is a great host - she waited for us at the apt even though we were late, had a bottle of win ready and even invited us to see the view from her terrace apt on the floor above. She was very helpful but did not bother during the stay unless we need her - the perfect balance between helpfulness and privacy.
The apt is very roomy, all-new(2015), modern and tastefully appointed. The view of il Duomo from all the windows is AMAZING! the pictures don't do it justice.

All in all a great apt and host - thoroughly recommend.
