It’s really a great apartment - clean, decorated with love, good for kids, comfortable and in a great location.
You’re about 10 min walk to the harbor (going to the islands), 15 to central station, 2 min to metro station, cafes, supermarket and small shops less than 5 min walk away. Really close also to walk to the old town and many restaurants. For its central location and for Napoli it’s also relatively quiet.
We stayed there as a family (couple plus an 8 year old boy) and we loved it. Had everything we needed and the location was very convenient.
Would recommend and stay again!
