In all, we didn't like our stay at all in this AL.
It is more than just an impertinence to rent out accommodation without being able to open a „real“ window. The dehumidifier, the weak fan or the cooling device that releases the warm air back into the room are not helpful. How is that supposed to work in warm July/August? Only one much too thick and uncomfortable towel (large/small) per person for 4 nights is also not acceptable. The sink in the bathroom is very difficult to use and there is to little space at all. No kitchen roll, no originally sealed water bottle complete the impression.
It wasn't good value for money for our feelings.
I definitely can not recommend this AL to future guests.
