The apartment is in a very central area, just a couple of blocks from the magnificent Duomo and the Duomo metro stop, which is a 5 minute walk, which made getting around Milan very easy. The apartment is fairly large for the location, but with a choppy layout, all in all it met our needs. The host had left a bottle of bubbles and some cookies for us, as well as local tips, all of which was very kind. Check in was easy to arrange and efficient. The elevator is handy, right outside the apartment door.
It is quite a busy part of town, which meant it was noisy. The courtyard below houses the recycling area and someone (we think it was the restaurant downstairs) crashed several large bins of recycling in to the recycling in the morning hours. Because of the courtyard, it was very loud, and was a bit disruptive. The restaurant allows guests to stand out front (adjacent to the front door of the building) and mingle, which can also be noisy when the restaurant is open. There was also construction within the building which was noisy and kept us from sleeping past 8am or so. Neither thing could the host prevent, but something to consider if you are not naturally awake by 8am (we were out late the three nights we were there, so it was jostling for us). By no means did we expect it to be silent constantly, but this was a lot of noise for a good part of the morning and throughout the day and evening, something to consider if you are even a bit sensitive to this kind of thing. The ensuite bathroom is tiny, which is to be expected. The shower in the ensuite only ran hot water - we informed the host who I am sure will correct this.
