We are seasoned cruisers and chose this cruise for a convenient way to travel home from Rome after attending a wedding in Malta. Past Transatlantic experiences have been exemplary on Cunard. We cruised on the Marina last year and anticipated a similar positive experience on the Sirena.
The ship is tired at best and in need of updates. Tiles surrounding the pool were missing and cracked. Oceania makes a very bold claim to have the finest cuisine at sea. Only Red Ginger was able to live up to that expectation. The other venues were just average at best with most food too salty.
Booked a Concierge level room with no advantage over a standard room except for the laundry service. There was significant vibration at the rear of the ship.
