This was our second cruise on Oceania. We received a lot of press on the new Sirena. We booked a Penthouse SG2 with no specific stateroom. This was a first for us not having a Stateroom; one of their promotions. We were going to be in Europe so all seemed good; bad decision.
We did not realize nor did our travel agent, that Oceania advises you of your stateroom the day before sailing. Thus you options to select another stateroom or cancel was not an option. My recommendation would be never to book a cruise without you knowing where you will be.
As to the ship, the Sirena is a 17 year old ship and it still looks like it. Other than make all the staterooms smaller to gain more revenue, it is a mystery as to where the money went.
The biggest shock was the size of the Penthouse. It had no closets and very limited space to put your clothes. Any cruise over 12 days would be an issue. The bathroom is a joke. You can almost take a shower, go to the toilet, and shave without moving. The width of the bathroom is so small it is hard to describe it. The shower is approx. 3’X 4’
I feel sorry for the passengers that did not have penthouses.
I strongly recommend you stay from this ship if you want to experience a great cruise; there competitors offer such better choices
