I just spent six nights at Ludovica's apartment, and I cannot recommend it highly enough! Ludovica was a great host: she was always prompt in responding to emails, she was there to meet me at the apartment when I arrived, and she had all sorts of helpful information for what to do in the city. The apartment was clean, well-appointed, and well-located. Out one window you have a beautiful view of Capodimonte, out the other window you can see Vesuvius. You really are only two minutes to the Cavour Metro station, and barely five minutes to the Naples Archaeological Museum. I will definitely be back!
