We were just on the Rome to Istanbul cruise on the Nautica. The itinerary was fabulous and we can't wait to go back to some of the places we visited and spend more time there. We spent 4 nights pre-cruise in Rome and 2 nights post-cruise in Istanbul.
Service - The ship's staff was excellent and we had wonderful service from everyone we encountered. Every staff member we came across took a moment and greeted us with a smile and were all very good at making sure we had everything we needed to have a good cruise.
Food - Grand Dining room food was very good, we only had slow service there one night. Tapas/Terrace food was also very good and the best buffet we've experienced on our cruises. Toscana was very good but make sure you have an empty stomach when you get there. Polo had excellent grilled food, make sure you ask them about what they consider rare, medium rare and well done. We ordered medium to get what we usually consider medium rare.
