The best apartment ever: perfectly located, fully equipped, truly clean, big and decorated with an amazing taste! It is even better in reality, than in photos. Two beautiful terraces can charm even the most fastidious traveller. Honestly, you don't even need Naples: you can easily spend your vacation in this apartment with the view to the real Italian residentials :) There is the wonderful pizzeria near this apartment, you can order a delightful Napolitano pizza "take away", if you want to take some rest from life speed of this city. However you should definitely visit Castel dell'Ovo in Naples and the ancient city Herculaneum.
I wish all hosts were so friendly and helpful as Marcella and Lucias: they know how to welcome guests.
Definitely I'd recommend this place and 100% will stay here next time I'll be in Naples.
