The best location in the city, in front of Umberto Gallery, few minutes to the sea, in the heart of old part of Napoli and the most interesting part of it, Spanish District. Everything is very close + metro station is just in nearby, so everything is just at your fingertips.
The flat is very spacious with nice place to sleep. We did some kind workation here, so it was perfect, because wi-fi connection is also very good. In the flat there are also interesting books.
But probably it's not for everybody. Everybody should be aware of few things, just to choose consciously this place (which is awesome, if you are looking for something like this😉): it's dark during whole day and you have to use artificial light from the morning, because flat is quite big with only one window to the patio, second: it's not high standard and some things are old or a bit broken, like toilet button (but everything is possible to manage, it was not a problem for us, it depends on your needs).
