Oceania Cruises said it has completed a refresh of the Sirena as part of the line's $100 million OceaniaNext program of continuous improvements.
The upgrade included some features that were not installed on the Insignia, the first of six ships in the OceaniaNext upgrade sequence.
They include new doors and full-length mirrors in each cabin, new wall sconces in the spa, additional crystal chandeliers in the public spaces and stair lobbies, and 100-volt sockets on each side of the bed in cabins.
New art has also been commissioned including a work by the line's executive culinary director, Jacques Pepin, which will hang in the restyled Bar Istas, the ship's social hub and coffee bar.
At the center of the ship, the deck-and-a-half tall French-glass mirror that crowns the ship's reception lobby and grand staircase displays a hand-painted willow tree meant to symbolize "balance, learning, growth and harmony," according to Oceania.
Nearby in the reception lobby is a commissioned piece by Soumiya Lakshmi Krishnaswamy that "seeks to capture the spirit of adventure that lies in the sea," Soumiya said.
The 684-passenger ship, acquired in 2016 from Princess Cruises, received $40 million in improvements before being put into service at that time by Oceania.
