This is my first river cruise so I don’t have a comparison with any other cruise line.
I started with an optional 3 days in Prague where I had an excellent guide. In fact, on all the excursions I went on the local guides they use were excellent.
I met the ship in Linz and embarkation went without a hitch. My cabin was comfortable and very clean. I was traveling by myself so can’t answer for the space available for two people.
It was perfect for me
