Nice apartament in great location. You may think that is far from centre, and yes-maybe is a longer walk, but through beautiful alleyes near coast, restaurants and port with beautiful views. So for me longer walk do city centre was a plesaure.
In apartament you can find everything you need, its comfortable and modern. Host is kind and comunicative. After small issue during our checkin, everything was ok.
One tip: This apartament is a separate place in bigger apartament. In this bigger apartament are two separates rooms (one is this place where we stayed and which I’m describing now). So in one place you have to seperate rooms with common entrance and common hall. And first night was great and quiet, but second night- didn’t because of new guest in second apartament. Walls are tiny and you can hear everything from next room, including for example using shower or speaking. For me it was a problem, cause I need quiet at night to have good sleep. So you have notice, that if second room will be busy, it wouldn’t be enough quiet - if you care abut it.
But overall- I recommend you this place to stay in Naples.
