Ship Reviews

Avoya Network
customers say
Oceania Sirena receives high praise for its attentive service, excellent food, and intimate small-ship experience. Most guests highlight the quality of the staff, well-maintained cabins, and diverse itineraries. However, some reviews note areas for improvement, such as inconsistent service in certain venues, crowded buffet areas, limited dining hours, and expensive or underwhelming excursions. Entertainment is generally good but not always up to the level of other aspects. Internet connectivity and communication could be improved. Overall, the ship offers a refined, relaxing cruise with a few operational hiccups.
