Maria was very nice and showed us kindly everything we might need to know about the apartment. It's a great place to stay in Naples because you are in the middle of the centre (other tourists will take photos of the courtyard that you're in, even of the house!), there are nice places to eat all around, and nice museums like Madre and the museum of archeology close by.
The house is very comfortable and clean. Maria takes good care that everything is in order :) she even left us breakfast things to eat, which I never expected so this was a good surprise. Thanks!
