We liked the itinerary and the cruise line. Regent is expensive, but you don't get nickeled and dimed on board. The size (small) of the ship also made it attractive.
My mjain complaint was the lack of activities and the lack of variation in the activities. Since my wife and I like "brain" games - trivia of various sorts, this cruise was lacking.
I also would have liked a bit more variety in the breakfast and lunch buffets, and missed having an evening buffet. However, the food was good and well prepared.
Good, spacious, well appointed cabin, Only complaint was pipe noise in bathroom and closet.
