From the moment we approached the pier we noticed this was a very modern vessel, much more than those "old" ships that were built just five years before. The attention to detail in construction and amenities (save one or two exceptions - I'll get to that in a moment) were spectacular. Even better, the service and attention provided by almost the whole crew was higher than expected, and of course, expectations of service in cruise ships is quite high.
Here's a list of things that were awesome (in no particular order):
Stateroom service (thanks O'Neill!)
Great cabin for the price. Bathroom toilet and shower pressure and efficiency were much better than expected.
