We boarded in Copenhagen for a 7-night Baltic itinerary that visited Helsinki, St. Petersburg, Tallinn, and Kiel. All four cities were wonderful.
The ship was great. It was always clean, didn’t seem overly crowded.
I did find that Europeans were pushy and rude and also had little to no manners at the buffet area and at the elevators.
The cabin was great. It was clean, comfortable and well kept.
