Chose this cruise as we like Oceania, embarkation close to home, and because of the port calls around the North Sea and part of Southern Baltic.
The first port in Faroes was cancelled to everyone’s disappointment, replaced by Invergordon. Which I really enjoyed, to my surprise. Otherwise everything went to plan and we thoroughly enjoyed the mix of other ports, particularly Stavanger and Oslo.
Sirena is a nice ship but I would avoid it in the future unless the itinerary is outstanding. Like Regents Navigator, the sports deck is at the bow end and unusable unless in port. As the stern end is occupied by staff deck and indoor venues except for a section of the buffet, there is not enough deck space away from the pool area. American cruisers and American ships are indoor orientated - finding a lounger by the pool was easy. The pool itself is tiny and only suitable for a dip. There were very few outdoor activities and no outdoor entertainment.
Small, teeny tiny shower-room, plenty storage good balcony. Immaculately kept but smell of poo in corridor - always.
