The apartment is very centrally located, extremely close to the cathedral, in a pedestrian shopping street. It is a great location, and it is very convenient in order to visit Milan. The only - extremely minor - drawbacks about the location are that there are some advertisement screens outside, as it's a shopping area, and that a small vibration can be felt from the subway or tram.
The apartment was extremely clean, well-arranged and convenient.
Mauro is a very responsive and nice host. All his instructions were extremely clear. He also answered remarkably quickly and efficiently when we had a minor question about the light, and this was fixed right away. Many thanks for this!
To summarize, this is a great place to stay right in the heart of Milan!
