I have to confess I didn't spend too many hours in this hotel due to Napoli's nightlife :o=)
However, the location is cracking (500 m from the railway station), the check-in was smooth and the room clean. The staff was also helpful in directing me to various places.
I couldn't taste the breakfast, but the double bed was of good quality, and the air conditioned worked fine.
Can't really complain for 89 euros!
Probably the location is its best asset. However, be careful in that area at night (i.e. take a taxi if you're going back after dusk).
Directions: When coming out of the main railway station (Centrale), turn left and walk for about 300m until the traffic lights, then take a left again. The street is called via Ferraris and runs alongside the rail tracks.
