The boat itself is very nice. The decor and surroundings are tastefully done.
Cabin is a good size.
Food is good although there is not much variety among the different restaurants.
Excursions are pricey and better deals can be found elsewhere online.
Working level staff (i.e. not Germans) are friendly and nice and do their jobs well.
German management staff are all young (20s) and don't seem very knowledgeable. If I asked one question to three people, I would get three answers. They seem to be enjoying their 20s and also on holiday. Their knowledge of visas and other key issues was lacking.
Always trying to up sell on items not included in all inclusive price, yet poor communication on disembarking and do not provide shuttle services at some ports - with no prior advance notice.
On board language is German, although working level staff are better with English. All activities are in German, so best to avoid Tui if you don't speak German.
Cabin is a good size for two people. Three adults would be too tight.
Shower had strong pressure and housekeeping comes by twice a day to refresh room.
