We are seasoned luxury cruisers, based in Switzerland, and booked SIRENA because of the itiniary from Buenos Aires to Lima on the 11th of November 2017. Comparisions are with a view to other luxury ships, specifically to SEABOURN.
The much advertised food on SIRENA is a fact in the dining room and speciality restaurants, somewhat less so on the buffet, but still good. The meals are well selected and offer a good choice every day. It is somewhat difficult to get a reservation at the two speciality restaurant though, because unless one has booked before the cruise even starts, it becomes very hard.
The ship itself is like an elegant older lady, which means that staterooms are somewhat smaller than usual, but are always well cleaned. The public areas are certainly nice in the "grand old style", but don't expect modern or the "glass look" seen on many newer ships.
