We chose this cruise because of an itinerary that included southern Italy, Greek Islands (including Santorini and Mykonos) and Venice. After we booked, the Santorini port was changed to Gythion. This was very disappointing since we considered Santorini an iconic Greek island that we did not want to miss. As it turned out, weather prohibited us from tendering into Mykonos, so we missed both of the islands we had been excited to see.
The embarkation for the Sirena was very smooth and quick, with our luggage being delivered to the room very promptly. All of the crew and port staff were friendly and made us feel quite welcome.
Our stateroom was an inside stateroom. The room was about the size you would expect, and had lots of storage. One drawback is that my husband's suitcase did not fit under the bed so he eventually shoved it under the desk area to get it out of the way. Although the room size was not bad, the bathroom size was very bad. My husband and I are both on the normal to slim side, and we could barely move around in the bathroom and the shower. We had to shut off the water in the shower in order to soap up and then turn it back on to rinse off. I hit my head on the cabinet above the sink when trying to brush my teeth. While it was less than comfortable for us, I cannot imagine how it would feel for those who are not normal to slim body types.
