Liliana and Claudio are excellent hosts! They met us at the metro station and guided us through the streets of Naples (which is a must, if you are a first time visitor). They provided us with pastries and drinks upon arrival and were very thorough in advice. The apartment is quite spacious (there were four of us). AC works fine, although it doesn't seem to be needed too much, even in the summer. You are in a a real neighborhood of Naples, so expect lots of activity in the street until things calm down at night. However, this lends the area an authentic feel.
