Fundamentally this is not worth the price. A kitchen is NOT a hotplate on a work surface by a sink, which is all you get; not even a microwave.
Yes, the cabin is a fun experience for kids, but the second 'bedroom' with bunks is incredibly cramped & the cabins are all packed in tight together. With young children, the noises nearby, in the evening, can be really disruptive.
The cleaning staff are clearly overworkes too: there were stains on the mattress protector (see photo) and the sofa had food crumbs on it. (This is a management failure of organisation, not the cleaners'.)
Lastly, if you're required to washup and put things away before leaving (or be fined €30), is it fair to expect some washing-up liquid to be provided.
