Embarkation/Disembarkation: Both were handled very efficiently in Copenhagen.
Ship condition: Some of the reviews I've read about the condition of the ship make it seem like the Zuiderdam is an old rust bucket on its last leg, which is certainly not the case. I didn't notice any worn out carpet or furniture on the ship and it was kept very clean. That said, it is an older ship and the décor is fairly dated, but it is well maintained.
Main Dining/Lido/Room Service: Other than the first night, when both our meals were mediocre, the food in the main dining room (MD) was consistently good, except for breakfast (frozen, deep fried McDonald's style hash browns, cold toast and barely warm eggs.) After our first couple of breakfasts in the MD we either ordered room service, promptly delivered at the time requested, or we eat in the lido restaurant. The omelet station was excellent.
Typical verandah cabin with small love seat sitting area. Plenty of storage. Bathroom was compact, as is usual on cruise ships. Preferred the tub/shower combination over the shower stall I've experience on other ships. Cabin was located on port side near the stern. I prefer this location since it provides quicker access to the lido restaurant and main restaurant.
