We stayed at the Smart Hotel for 2 nights (family with 2 kids plus dog). The hotel is situated on the dock in the harbor of Napoli, inside the old harbor building. Access to the dock and to the hotel is through a checkpoint with a guard, which is good and it provides a bit of extra security. We got a free upgrade to a room facing the water, which was very nice. The beds were comfortable, the bathroom was clean and modern, and sleeping at night - even with open windows - was surprisingly quiet even if a ferry or a big boat would arrive at the next dock. The staff at the reception or at the breakfast room or elsewhere in the hotel has been always very friendly and very helpful. The breakfast was included and the selection at the buffet was rich and had everything, for sure well above Italian standards. Parking of the car was possible just outside the fenced area, in a guarded parking lot (€15 during weekdays, €25 during weekend days), so also pretty close (50m) to the hotel. Overall, we think the hotel was the best choice we could have done in Napoli. Highly recommended, we would come again.
