We really loved staying in Caterina and Carlo's apartment. Carlo was gracious in welcoming us in, orienting us, and recommending some excellent spots and eateries in Napoli. Other reviews have covered what you need to know about the location being accessed by furniculare. The great part of this is that you are a bit outside of the hectic parts of the city, and it does live up to its billing of 'naples as a village'. It means for just a bit of extra planning to get around but we really liked being able to get to the quiet of the apartment in between being in the city. And, being above it all is nice. The one thing to know to expect is that the bedrooms are not exactly isolated - one does not have a door, though is private on another floor, and the wall on the other does not go all the way up to the ceiling, so everyone can hear everyone else get up and walk around in the morning. We are fine with it, but it is good to know.
