We boarded and informed the ship had only one engine. This was replaced 12 days into our cruise. This meant we were unloaded and loaded at small jetties spent hours on coaches and less time at our destinations. A lock broke near Frankfurt which put us back another 12 hours. The ship is not fit for purpose. The toilet system broke down 3 times. Internet very bad reception. T V was in German had not been switched to a English satellite. The food was O K but deserts terrible. Coffee in the restaurant to strong and cold complained to the Hotel Manager but no improvement. Staff in restaurant needed training not serving ladies first, reaching across to deliver or pick up plates. The temperature control in our cabins did not work. We some times had to endure unpleasant smells when docked closed to other ships. The ship needed net curtains to most cabins for privacy when in port or docked next to another ship.
