The room in Riviera di Chiaia is very nice, perfect size for a couple! We spent there 8 nights, during the day we have been visiting around, the room was perfect to sleep, have a shower, relax!
The location is not very very central, you will need to take a bus or a metro to move, but everything is very easy to reach! Further more is very close to the lungomare (1 km of very pleasant walk in front of incomparable view of the city and Castel dell'ovo), the area of Via di Chiaia and Via dei Mille is also very close by walk and it is the place to be for going out in the evening :)
Paola is extremely nice person and took very good care of us in every circumstances.
