We had used Costa once and were not very pleased, the only reason we chose it again is because it was the only cruise that we found that would go to Norway on the dates we had available.
The ports of call were spectacular, enjoyed the views, the fjords, nature, falls and train rides.
It was a multicultural experience with people from a lot of nationalities.
Carpet needs shampooing. The sofa was a little worn. There was a lot of noise coming from the music below on party nights. Even with ear plugs I could hear it.
We were assigned this cabin, with the rate we paid we were not able to choose, but were happy that our view was unobstructed.
