The apartment was exactly as described, the location is only a 3 minute walk to the Duomo and within walking distance of great bars and restaurants. It was very clean and the beds were very comfy!
Only things to note were the noise from the trams outside, if you are a light sleeper you should bring earplugs. Also there was only 1 mirror which was in the bathroom, it would have been good to have mirrors in the bedrooms as there were 4 of us staying there.
Apart from that, we would definitely recommend staying here for a city break in Milan!
