This is an excellent location, very safe, beautiful neighborhood. Nice restaurants, coffee places, local markets, etc. Most of the tours will pick you up from Piazza Sannazaro which is 3 minutes from the apartment. The best hazelnut gelato is at Ciros and of course the metro station is 5 min away.
Paolo is an excellent host, good communication and very attentive to your needs. My daughter and I had a beautiful stay.
