Stayed for 4 days, early check in, late check out was no problem at all. Marta is very quick responding and very helpful to get you around the area.
Casa Marta is located in Vomero, top of the hill very nice and safe place. The view is amazing, metro is around the corner.
Thanks again to Marta and her father Guiseppe who helped us with the check in. And her mother for making the bed!
The couch which can be transformed to bed was very comfortable.
Overall a perfect place to stay in Napoli.
