We have just returned from a week staying in Mimma' s apartment. This is in a great spot in the city, with fabulous views across to the Bay.
The apartment is just the right size for a couple. Mimma has fans in the rooms and there is air conditioning too. The apartment is clean, comfortable and safe.
We spent most of the time we were in the apartment on the terrace which is excellent. Naples is a noisy, vibrant and interesting city and worth exploring. There is a lot of work being done in the area to develop the Metro and the City Park between Riviera di Chiaia and Bay, but this doesn't inhibit anything.
It is easy to walk from the apartment to the centre, either through the via and vico of the area or round the shore, past Castel Dell'Ovo. The metro at Amedeo is a 10 minute walk from the apartment and takes 10 mins to Napoli Centrale, or the 151 bus, from across the road, takes 10 mins to get the the Port and then to the islands, Sorrento and Positano.
Vomero, Chiaia, the Spaccanapoli and many other areas are worthy of a leisurely wander.
Enjoy your stay!
