This was my sixth cruise, from Buenos Aires to Santiago trough the freaking waters of Cape Horn, actually sea was mostly calm.
Embarking at BA took 2+ hours waiting, passengers of 3 ships had to pass migration controls, but finally got to our cabin and baggage was there.
The ocean view cabin was spacious, with a 3 seats couch convertible to bed. Having read in other review that the steward after the first night never returned the bed to sofa, I was direct about this topic with a tip on hand and we could enjoy our couch every day. This is important because the TV is on front of the sofa and is not pleasant to seat on a bed with your back on the wall.
Cabin E675, good location, low sound from engines. Only issue is far away from laundry
