Residenzia Pizzofalcone was a great apartment. It was very well maintained, clean, and unique. Giuseppe and his crew were very attentive and friendly. There is on-site laundry which really came in handy for us and Giuseppe pre-ordered a taxi cab for us since our flight out was very early in the morning.
It was a little tricky finding the place. We used google maps to get to the street but since the streets and buildings are very different where we're from we couldn't find the exact address right away. Walk past Pizzeria Piscopo (great pizza right out your front door, btw) and look for the giant wooden garage door that has a small door built into it. It almost looks like something from a church. To the right of the door there will be a call box with all the apartment names. Then you just have to buzz Residenzia Pizzofalcone.
There are many restaurants and attractions within walking distance.
I definitely recommend staying here when in Naples.
