I am from the Netherlands
Hans was a pretty "testy" and complicated guest. He kept complaining through out his whole stay making two other guests deciding to leave him alone and cancelling their reservation. He clearly did not take the time to review the place before making his reservation and was expecting a 5 star hotel and not a family/ student house.
we wouldnt recomend him for other hosts and definitely wont have him again with us.
he created a very dense and complicated atmosphere with his continous fighting with his family
