We have felt very fine in Marianos appartment. Although the appartment is in the 4th floor, it wasn't too warm. And by night we used the air conditioning.
We've got good advices from Mariano and his family which things are nice to visit. It was only a few minutes to walk to the next train station so we never used our car and went everyday by subway.
we had a great time in Napoli !
Thank you Mariano
