I would highly recommend staying here. first of all the location is great! Only 15-20 minute walk to Napoli central. 15 minute walk to the port if you want to get a boat to places. 5 minute walk to the metro.
The street is busy and loud, but the balcony doors completely block out the sound! The apartment was very spacious. It has two large rooms, with nice high ceilings, a comfy sofa bed and had all the amenities we needed for our stay!
Via San biagio dei librai and via dei tribunali are popular streets in naples and are both very close.
I would 100% stay here again!
