I give this property a 5 star for the following reasons.
*Giorgio and his wife went out of their way to help us find the place; even driving to find us. Our Italian and their English was limited, but we made it through it. The Igloo gelateria on the beach was a good meeting spot. Everyone seems to know about ice cream.
*The apartment was very clean and has a nice terrace right on the beach. They left us beach towels and wine and made sure we were comfortable, all questions answered, before they left.
*We have been traveling all over Italy, from Cortina/Venice to La Spezia/Cinque Terre to Positano/Praino. Although the beaches and cliffs in the other locations are more beautiful, Nettuno offers a beach with sand and swimming that is easily accessible. It is also just south of Rome about 45 mins. so a good resting spot and easy travel in access.
We did find a couple local restaurants that were very good and beautiful. Check out Elisio; it is just a 5 min walk. It has a beautiful entry, family owned and run and quite good.
There is also a restaurant in the tallest hotel nearby. Don't be fooled by the entry, we found the veal delicious. What a cheap dinner that was and so good. I think we spent 28Euro for two Veal dinners, salads, coffees and two beers. Obviously a local spot.
We walked to the American Cemetery. It was about 20min walk and worth the visit. This is probably what we enjoyed most about Nettuno. otherwise I don't think the city would be worth a visit for us. it was just a good respite when travelling from the south toward Rome. The beds were very hard. Although I have to say they have been almost this hard in every stay we were in.
Make sure you keep the keyes with you at all times. There are many locks to go through and you will need the keyes to get in all doors and to enter and EXIT the Free Parking garage.
