We had a very nice time at Maria's place. The apartment is ideally located in the hills around Napoli - just a few minutes away from the center, yet without all the noise of the touristic areas. Maria was very kind and provided us with all kinds of useful information. The room is comfortable and gives access to a great terrace. Only the shower proved to be quite tricky and it would probably have taken us some more time to learn how to shower in such little space without flooding the whole floor...
Still, highly recommended, we would definitely come again :)
