Ok, I could only give 4 stars...because of the unrefurbished ship. But otherwise, all was perfect. Silversea will get a new ship in 2020, so if having clean, comfortable, but not shiny new accommodations will bother you, wait a year. You will not be disappointed with the organization of the expeditions and the care taken to ensure safety.
Plus, the food is excellent even though the Galapgos has significant restrictions on food import (true for all cruises there). The Grill Restaurant was particularly fun at lunch with a keyboardist providing upbeat music.
Overall, I'm glad we went when we did as the ship was just fine and really didn't detract from the main event of seeing the islands.
This class of cabin has no balcony but is spacious and has a decent set of windows.
