The apartment is very modern and nice. It's in a central location so you can easily walk to the tourist attractions. We only took the metro/funicular once to go to Castel Sant' Elmo; otherwise we walked everywhere. Marco, Valentina's brother was there to receive us at the apartment. He was very helpful and nice. He even scheduled a taxi driver to pick us up the morning of our departure. Thanks Marco! Overall we had a good experience. It can get noisy outside the apartment, it seems that Naples people stay out late at night, but if you are a heavy sleeper or wear earplugs you will be fine.
