The appartment is very spacious.
It has everything you need; kitchen, bathroom, big closet, living room.
The bed is comfortable and the air conditioning is a nice extra, since the temperatures are quite high in Naples.
If you go up the street you have the bar where you can have breakfast, down the street you get to the lungomare (promenade on the sea) within about five minutes walking. Perfect!
Metrostation Mergellina is nearby and an easy way to get to the central station and historical center.
In Mergellina there are also plenty of nice restaurants and bars near the sea.
Would definitely recommend it!
