The apartment is really cute, clean, spacious and peacefull. The only point to mention is that the kitchen isn't so well equiped if one might stay for a longer period ;-)
Situated in the Chiaia neighbourhood it is a good place to have a walk along the seeside which is near there. Going to the historical centre takes some 30 mn from home including the short walk from the house to the piazza Amedeo (where you can then taking the metro until piazza Cavour for example).
Adriana is a very gentle host and will make sure that you feel confortable in the apartment ! The communication was very uncomplicated, precise and she always got us very fast responses.
