Our stay at Susanna's place was very pleasant, if short. Check-in was easy, and when we entered the flat, there were drinks and snacks set out for us, so we didn't need to run to do our usual shop run for the basics. The location is amazing--easily walkable to the Duomo and castle--, though it does get loud at night due to the bar across the street. Nevertheless, the area is quaint, and it was nice to look out over it on the balcony. The place is clean, and there are personal touches (e.g., little, cat-shaped hooks in the bathroom) throughout the apartment.
Other than the late-night noise, the only negative is that there only seems to be enough hot water for one person to take a short (5-10 minute) shower. I've had a few cold showers in my life, but they were either while doing fieldwork in Egypt or when a hurricane knocked out my power for a few days in Florida, not while staying in a modern apartment in Milan for nearly $100 a night. That's the only reason I wouldn't give Susanna's place 5 stars on value for money. Otherwise, I loved the apartment and, if the water heater is sorted out, would gladly stay there again if I return to Milan.
