This apartment is in a really good location for seeing the sites around Naples. The neighbourhood is lively and a little noisy at night, but when you're so many stories up and the windows are closed it's not an issue! It was great to be close to Piazza Bellini and the bars there, as well as lots of the main sights in Naples including Santa Chiara and Cappella Sansevero.
It is worth noting that there are a LOT of steps to get up. Like a lot. However the upshot of that is the amazing views, you can see all the way to the sea.
There are two bathrooms, but we found that you could only get hot water in one shower at a time. Not a huge inconvenience but worth noting.
Would highly recommend this apartment, but if you do have any mobility issues then it's definitely not one for you.
