What to expect ...
Very uncomfortable bed
Access to the loft area for the twin beds is dangerous
Don't expect comfortable seat on the toilet - unless you have short legs as it is a side-saddle job, with the resulting problems
The shower has very low water pressure; there is a tepid supply, the shower has not been thoroughly cleaned for a long time as it smells of mould and it is mouldy around the framing (brown and sticky)
The bathroom sink is slow to empty
The dishwasher instructions are in German - not helpful if you don't understand the language - and whilst it makes noises and heats up the water it doesn't wash the dishes. A bit pointless really.
Outside, the pool is (literally) a pond - with fish, fish poo and crawling creatures. Sanitary? I doubt it.
I could go on but hopefully you get the picture.
Is it worth in excess of €100 per night plus cleaning etc. NO, definitely not.
If you need to stay in this area, you should seriously consider somewhere else.
