The apartment was much bigger than expected for price point and it being Europe city center. I can see a family of 4 or 5 comfortably staying there. We arrived close to midnight so self check-in (and check-out) was a great option for us; it was also seamless and easy. The metro and bus stops are close to the apartment and the train station was only a 20min walk for us. It is a 4th floor walk-up (it's Europe), which is okay for me and great after a day of eating delicious italian food. There are a few delicious pizza restaurants (notably La Figlia del Presidente) less than 5 mins walk as well as a cafe where we had a cappuccino and cornetto each morning (Caffe Ciorfito). Paolo and Pier were quick to respond to all our questions, they were always available. Highly recommend this apartment. Will be back if in Naples.
