This AirBnB is very centrally located in Milan and very close to the Duomo, which is great for tourists. However, a few things to note are: the apartment is very small (smaller than it appeared to us in the photos), and particularly the bathroom is tiny. The entire bathroom becomes a shower when you turn on the shower (meaning, when you turn on the water, it gets all over the toilet and sink as well).
Also, in our experience, we had problems with communication with the host, who continued to insist that we did not let him know when we would be arriving even though we messaged him three times (once several hours before arriving, once when we arrived in Milan, and once when we arrived at the building) with no response on his part. He only responded when we texted him, and then when he showed up to let us in, he kept talking about how we should have let him know when we would come in advance, and he did not listen when we explained that we had tried to contact him.
He did give a very thorough tour of the premises but one thing to note about our experience (as three women staying in the AirBnB) is that Marco made a few comments about women and "women's stuff" that made us feel a little bit uncomfortable during the tour.
But in terms of the physical space, it was a clean, well-located, and overall decent place to spend a night in Milan.
