The apartment is on the 7th floor (with an elevator), and we had an incredible panoramic view of the New Year's Eve fireworks in different parts of the city. The apartment itself is quite small, but it has a wonderful large balcony and all the essentials. No microwave, but there was a small toaster oven that worked well.
The apartment is basically in the "roof" of the building, so it has an angled ceiling in places. But it's generally fine as long as you remember to duck a little while passing those spots.
The location is great - only a short walk to the middle of the old city, but away from the busiest, noisiest areas. It didn't rain while we were there, but there are so many beautiful porticos and covered walkways everywhere that it would be easy to explore the city and still stay dry even in a downpour.
Marcello's cohost Camilla was very kind and helpful, with excellent communication and great suggestions for restaurants and sights in the city. Thank you for a lovely stay!
