I do NOT recommend. The flat itself is very beautiful and well maintained (a big + for the bathrooms with all sorts of shampoos etc), but the landlord is rude and unpredictable. He made a scandal of using washing machine in the evening, "because it's too loud" (which sounds like a joke in Naples, which is louder than a starting F16). Afterwards he was moody and ended with kicking us out at 11:00 because the new clients were coming. I wish them a better atmosphere than we had.
PS I must admit he had let us leave the backpacks after kicking us out (so that we can see the city without carrying them on us), but with an extremely unhappy face.
