We chose this voyage because the timing allowed us to complete an earlier Princess cruise; spend a week driving the northern lake region of Italy; pick up this cruise, and then put us in position to cruise back to the States. (We were celebrating our 60th anniversary/80th birthdays...while we both were still standing.) We've traveled Costa previously.
Costa Cruise Line may not be for everyone; it has been good for/to us. For whatever reason, some travel agents will not book you on Costa. If you find this to be the case and you really like your agent, book the cruise yourself and having done that, transfer the booking to your travel agent. Failing that, book the cruise yourself and forget the agent.
Costa, in Europe, caters to typically not less than 6 nationalities aboard the ship. Your announcements are therefore (typically) in 6 different languages! Italian, German, Spanish, French, Portuguese, and English. With the increase in Asian tourists, do not be surprised if additional groups are catered to. The preceding isn't bad, it just "is".
The cabin was Ok; there was a whirlpool (4 jet) tub but no separate shower. The balcony was extremely narrow.
Originally was to include Giverny but changed to (thank goodness) only Rouen. Very nice tour of a nice town. There would not have been enough time to enjoy both towns. Recommend this tour.
