The location of apartment is very good, just in a center of everything. I didn't really use metro but was walking around. it is close to famous restaurant Da Nennella, close to Centro Storico and to the sea. it is located in the center and I felt safe walking alone around and coming back late in the night.
Andrea was very helpful, he picked up me from Toledo station and helped with my laguage. he and his girlfriend are very friendly and welcoming.
Andrea offered me to have a coffee and to had some of his wonderful home made lemoncello. I had a really good time there. I was worried before about 4th floor but it was all right. Next to the appartment you can find many small shops, where you can but some delicious local food like cheese, bread, salami, fruits and many small restaurants which are quite good and not expensive. in this place, you can see life of normal, Neapolitan people, mix with them and feel like at home.
