I would never sail on a Lueftner Amadeus cruise again. No hot water for the shower for 4 of the 6 mornings. Rooms unbearably hot - several of us had to leave the dinner table to cool off outside during meals, despite repeatedly begging for them to turn down the heat. Always late into port, which meant that our land tours were rushed and cut short. The "hotel" manager was absolutely rude about complaints about the lack of hot water, blaming the passengers for just not knowing how to turn on the water -- and then reversing that and admitting there was a problem with the boiler. The captain - even ruder and more unresponsive - claimed that the lack of hot water was due to the Americans who "ran the water for 10 minutes before getting in the shower." Then when we asked him to repeat that so it could be recorded, denied he said it. Some of the staff were very kind and helpful, but I wouldn't subject myself to another cruise on this line if it were free.
On the walkway to the restaurant, it was OK, but the hallway was like a sauna. The beds felt like wooden planks with a thin mattress on them. No room for a suitcase. Telephone didn't work, nor did the intercom for general announcements Worst was the lack of hot water for showers in the morning. Nothing like cold showers during the cold December month!
