Perfect central location, next to Dante's museum, coffee shop under the windows, bars, bistros/restaurants nearby. The apartment is nicely furnished, is clean with big rooms. To check in you need to make a call, set the time of arrival and this guy will meet you in front of the building to show you apartment, give you 1 set of keys and info.
Some cons:
It was cold in the apartment. It is an old building, the warmth goes away so quickly and we were there in February. In each room and in the kitchen is AC, but it's not enough. You need to turn it off in the night, in the first room was AC so noisy, we couldn't sleep + there are some restrictions about temperature. But in the summer it could be great.
You need to throw away trash - or just leave it on the street, no trash cans available on the street. It's not big deal, but I was surprised by that rule.
Overall, our stay was good, I would come back, but in the summer. Thanks.
