We had a generally nice cruise (2 adults, 2 children). The crew was very polite, the ship very clean and well decorated, the program of free entertainment very rich. However, it was relatively expensive everything it was not included in the cruise package (excursions [well organized] etc). Our cabin was in the size I imagined, well climatized and served.
No problem with the food; well cooked and satisfactory variety. You can also fill small bottles with water on the 9th deck.
No smoking rules were strictly kept throughout the cruise.
As it was my first cruise, I cannot have a view about the size. It was fairly comfortable, as it was the toilet, too.Perhaps two persons would feel more space there. Although it was visited twice a day by the steward, I do not remember the sheets to be changed more than once. The mini bar was well equipped, but not the toilet; only the paper, a single piece of soap and an invisible lotion over the shower.
