Good cruise, some things to watch.

Operationally, the cruise was excellent. Always punctual, and the ship is kept very clean. Our cabin was a very nice rear facing balcony with good closet space.

Food wise, pasta and appetizers were always good, but proteins were not. The only proteins we enjoyed were the extra cost burgers and the duck on gala night. Fish seemed to taste "fishy". We ate in the club restaurant one night, service was outstanding, but the filet had an off taste. It was however cooked a perfect medium rare. Salads on the buffet were very good.

Piu gusto drink package was a great value. Wines were good, as were cocktails. Espresso every bit as good as on land in Italy.

Entertainment staff keeps things fun. The white party was the best I've seen at sea. Shows were below average for a cruise as were lounge entertainers. 

One nice touch, they had an English speaking (from England) customer service rep who always asked how things were going and genuinely seemed to care.

Would I take Costa again? For the right itinerary at the right price, sure. All Cruise lines have their pros and cons--Costa's strong points are fun, pasta, and espresso in my opinion.
