Let me start with the plus sides: great central location right at the main square (Rossi Square), yet reasonably quiet at night; well equipped apartment with lots of supplies in the bathroom and kitchen; fair price.
On the downside: mold in the apartment due to airflow problems, 106 steps up (truly for the sporty people, and try that with a suitcase -quite the workout), three small bedrooms - one without windows.
We did value also the air conditioning in the living room and in the hallway (none in the bedrooms, you need to leave the doors open to benefit from the hallway A/C). Also, be aware that one the two floors below you is a hostel, and next door a peep show (didn't know they still existed!).
