The place was small, but clean and comfortable for 2 people. There was milk in the fridge and some sweets and coffee for breakfast. The AC was only in the bedroom, but the apartment is small, so it's enough to cover also the other room (kitchen + dining table + other bed)
What I found not so nice is the area where the apartment is located. The street is "genuine" city center, close to the central station but also to the Teatro Massimo...but..unfortunately it's also a very poor, dirty area. Sadly that's now common across the whole city center.
Take a look at the address on google street, if that feels ok for you then go for it, for me was a bit too much.
