The 5 of us stayed in this apartment, which is located in a very nice area with a market and lots of shops and restaurants in the neighbourhood. The metro station also the Funiculare is easily accessible.
The communication with the company was easy, mainly via WhatsApp. The apartment is spacious , nicely furnished with lovely accessories (families with small kids may find it slightly challenging) with a well equipped kitchen.
I recommend it to everyone who wants to spend a few days and enjoy the hustle and bustle of Napoli.
