This was our first time on Koningsdam but the third time with HollandAmerica Cruise Line. Food quality - as expected. Food service - poor. Some of the food-servers have an attitude that they do not like to serve you more food when asked. Most of them have no smile on their faces. Lido Market cleanliness - poor. We observed how the tables and chairs/seats are being cleaned: one little green towel is being used to clean more than 10 table tops; all the food residues are swept from the table tops to the chairs/seats; the same towel is used to clean more than 20+chairs and seats; the same towel is used again to clean the bottom of the tables. There is a big white bucket underneath the dirty dishes counter but contains very little water; however, we are not seeing the little green towel is being washed in the bucket. The floor is vacummed while the passages are still eating. We are forced to lift our feet so that our eating area can be vacuumed. The coffer/tea/water bars are always wet. Dining room service - good. Stateroom - bathroom is a plus; our housekeepers are keeping our stateroom clead and orderly; they are friendly and cheerful.
