Umberta is a really lovely host, we were absolutely satisfied with everything. Umberta helps in everything, she phoned to her friends so as to get information about Lago Como for us. She offers you good breakfast, you can have all you need from the fridge!
The apartment is clean and the bed is comfortable, the bathroom is really extraordinary. It is very close to a metro station but you should calculate 15-20 minutes to get to the center. The district is very safe, we were on the 1st May and thanks to the Workers' Day all the common transportation stopped at 7pm and we had to walk home at night. It was a 30 minutes walk from the Duomo Square but we felt totally safe.
We would absolutely go there again if we travel to Milan, we recommend this place!
