This is an excellent base to explore Naples. You are right on the busy seafront where there are excellent restaurants, stunning views and lovely walks. The historic centre is easily walkable and there are very many sights, bars and cafes close by.
The flat itself is as described. It has a great, relaxing atmosphere - light, airy and spacious and comfortably accommodated us as a group of five. The apartment block itself is interesting and has great internal features.
Would definitely recommend.
