I stayed in Piera's apartment for 2 weeks. It really is what it says: a charming (and beautiful) apartment in the historic center of Naples. Location could not be better. The terrace is a big plus! Communication with Piera was very easy and pleasant.
The apartment is definitely spacious and I really felt at home.
My brother came to stay for a few days, and although there is not really a second bed room there is a comfortable sofa bed in the living room.
