I only did a 7 day cruise from Rome to Athens. But the ship had just come from the Caribbean and was doing a 21-day total Mediterranean itinerary, so many of the passengers had boarded earlier and/or were departing later.
Great ship, great food, great service, and awesome fellow passengers. However, the servers themselves did not come across as very personable, just professional. Probably because we were just coming out of the pandemic and it being early in the season, the ship did not seem very full -- which was great! Probably also because of the time of year, children were virtually non-existent. Only complaint was that I felt the entertainment choices could have been more varied. There was only one sea day on my cruise so it wasn't really an issue. There was a dance class, I think offered daily with a different dance featured daily, that was nice. It was not a party ship and the majority of passengers were over 30, probably over 45. More of a laid back and relaxing but slightly refined feel.
IA interior cabin was more spacious than I had imagined. I seldom (virtually never) saw the room service people, but the room was always nicely cleaned when we returned!
