We've just returned from a 12 day cruise from Rio to Buenos Aires. We met a great crowd of people and made several new friends. The food was generally of a very high standard although the portions were small like nouvelle cuisine - a started portion of 3 Tiger prawns is hardly going to satisfy most people.
The website stated that the Sirena was refitted in 2016. This is misleading - the speciality restaurants may have been but the common areas were very dated rather like a 3 star hotel. Very disappointing as we had only previously sailed with Celebrity and we were told that Oceania was a step up. I would strongly disagree.
The Staterooms (I prefer to call them Boxrooms) were minuscule and the shower rooms were like telephone kiosks and fitted to a standard that reminded me of an NHS hospital.
In summary I would say that the Sirena is past its "Sail by" date.
A lovely starting point which we really enjoyed.
Could quite easily stayed on board. Nothing special.
A lovely place. Thoroughly enjoyed visiting.
We did a private tour with friends. It's a very interesting city and well worth seeing.
Saved the best to last. We stayed on for 4 days after we disembarked. A wonderful experience.
