We chose the Stella Australis as the culmination of a 3.5 week trip to Argentina and Chile. Cruising had never appealed to my husband but he was attracted by the fact we would be trekking in remote places and, of course, visiting Cape Horn. He also liked the fact that it was a small ship.
We departed from Punto Arenas and had a few hours to explore the place and stop for a Pisco Sour which was nice. Both embarkation and disembarkation were extremely slick.
The ship is very pleasant. Being smaller than many cruise ships, you have a main dining room and three bars/lounges. The cabins are fine. We were in a standard cabin and had tried to upgrade but it wasn't possible however the beds were comfortable, the view good and the place was scrupulously clean.
Functional, clean cabin. The upgraded ones give more space but were harder to come by.
