I visited Naples with my two grown sons, 19 and 23 and I must say this is a brilliant holiday if you have adult 'kids' as they loved the city's vibrancy, history and coastal location. The single beds in the apartment for fine for them, even though they are now very tall! I love cities by the sea, and so I really appreciated the apartment's location for that reason. The apartment is totally as you see in the pictures, open plan and really wonderful. It had a very Neapolitan feel to it. I recommend https://www.stowyourbags.com/en/shop/naples/luggage-storage-naples-central-station/ for storing your luggage if you time to enjoy the city between checking out and leaving the city and I have lots of recommendations for the city too that we particularly enjoyed. But all in all, if you want to have coast, but also be in walking distance of the centre, this is perfect. I also recommend the taxi service that Davide offers - the 151 bus to the apartment from Piazza Garibaldi is fine, but it took a long time, and if you are travelling solo, you don't want to be at Piazza Garibaldi at night. The area of this apartment felt totally safe by the way, and I loved the coastal walk in both directions - as well as the Helbiz scooters along that path too. Thanks Davide. I shall be recommending this to all my friends.
