We spent 4 nights in Naples and Casa90 and it honestly exceeded our expectations. The apartment was perfect for us, over two levels with a great shower and big space on each level and probably the best location we could ask for. Each day we managed to discover something that was well within easy walking distance: Castles, the water front, local sotteranea, teatro Di San Carlo, piazza del plebiscito, lots of food -gelato, sfogliatelle, pizza fritte (to name a few..don't forget to try pizzaria Da Michele), and a waterfront with a stunning view across the bay to Vesuvius. Giovanni was great! Extremely quick to reply and helped us out to store our bags on the last day. We will definitely be back and hopefully soon!!
