My dad and I were doing a tour of Italy and Naples was our final leg of the trip. Dario's place is pretty close to everything. If you are taking the train/metro in, exit the University stop and it's not too far from there.

As far as the apartment goes, it did the job. My dad slept on the couch and I upstairs. It also has other essentials such as wireless, stove + cookware, washing machine and other things.

The only thing we didnt like was the bathtub / shower. You have to step extremely high (about 2 feet or so) to get in. Once you are in, it is extremely awkward due to its shape.
