Regardless of poor reviews that we read, we embarked on the Costa Deliziosa due to provided price discounts (~70%) for 2 x 10 consecutive days. And, the following is our personal opinion:
1. Food and its variety was very good in taste and the quality terms.
There was no liquid soap at all in the shower's dispenser over full 3 days regardless of monitoring the case right on 1 day to room cleaning lady and in the office. And, the major problem was the cigarette's smoke entering our room as soon as we opened the balcony.
However, on our second tour (Feb 01 to Feb 11 2019) the service man was excellent in maintaining our cabine #4336. Regardless of his cleaning duties he fixed not easy problem with not working TV and the lack of remote control.
