We had a lovely time at Giovanna & Claudias place! It's tucked away from the city so you don't hear too much when you're there. The kitchen had everything we needed. The aircon worked really well and is needed in Naples during peak summer. We felt very safe and enjoyed our stay.
It's not a bad location - it's just hard to get into the center unless you have a car or walk. There is a bus transport but it wasn't very reliable. We recommend if you stay here to walk the 25 minutes to the metro and avoid taking buses as much as possible. But none of this affected our stay. We had a wonderful time.
