This is a very nice little studio apartment and was a good base for us in Naples. It's very clean and modern, on a quiet alley, and is very close to the museum so easy to get around either on the metro or walking. We were within walking distance of Starita for pizza and also Piazza Bellini where a lot of young people were out for drinks at night. Antonio met us near the apartment and had a friend there to translate everything into English - including that a famous Italian movie was filmed there!
However this is really a studio apartment and not a 2 bedroom apartment (the two beds have one wall between them but are open to the rest of the apartment with only a plastic sliding accordion divider.) It is not a problem for 2 people or a couple but if you wanted to have more people it would not be private and the entire space is just very small for more than 2 people. Also the listing says there's an additional single bed - but there is definitely not room for one - there's not a couch or hangout space - so its really more of base for going out and exploring!
