We enjoyed our 9 night stay at Casa Salazar. Demetrio personally welcomed us to his flat with 2 bottles of tasty wine and a fridge full of cold beverages. Both wifi and air conditioning were very good (the latter being especially welcome during the heat wave in Naples during our stay). The apartment is stylish, comfortable and equipped with all the amenities for a great stay. The apartment is near a large supermarket (365 Sole), incredible pizza (50 Kalo--we ate here 5 times--try the 'Nduja, Ripieno Fritto, and Montanara), tasty coffee and pastries at Vittorio Caraturro, and seafood pasta at Il Miracolo del Pesci (a bit of a walk, not a fancy interior, but terrific seafood pasta). The subway is convenient to the main tourist areas (Cavour and Montesanto stops) as well as Napoli Cetrali, but be aware that train service appears to be less frequent on the weekends.
