We stood in the Apartment for a week and everything was great. It's a cute apartment right in the center of Naples in the Spanish quarters which is a very nice surrounding as I found but that depends on your liking I guess :D
The highlight surely is the terrace which gives this apartment its title. Very nice chilling up there after a long day and enjoying the soothing summer air on top of the city. Everything was clean and we had enough equipment to not having to care about anything basically. Only thing to point out is that the stairs leading to as well as inside of the apartment are very steep and narrow. For us it was no problem and in fact a nice leg exercise but if you have some issues with walking stairs this might not be the apartment for you. If not, there is nothing to complain and it's basically the perfect apartment to stay in Naples. Metro station is close (like two minutes walking) and you even have a shower on the terrace to cool you down on one of those very hot summer days as well a a freezer to help you enjoy your beer cold just as you like it. As you might be able to tell I am very much impressed with this apartment so I can only recommend it.
