silverfish in the hallway, sink, and shower - crawling on our toothbrushes. when I raised it with the host, she tried to blame me for not renting a newer apartment ("Maybe you just book in a more modern apartment complex next time visiting copenhagen.") (direct quote). she denied that there were any silverfish at that time despite acknowledging it as an ongoing problem in the apartment - she checked this problem the next daytime when silverfish are nocturnal so of course it's less likely she sees them in the daytime. see here: https://www.google.com/amp/s/www.rentokil.co.uk/blog/5-facts-about-silverfish/amp/
the cats are indoor and very friendly. however the litter box needed replacing at least daily - this was left in the shower for 2 days with 2 cats. you can only imagine how smelly and unhygienic that was in a room that's meant to be clean. silverfish are a direct cause of an unclean house - I will let you put two and two together.
all of this could be somewhat overlooked had the host given a conceding tone but unfortunately her refusal to take responsibility and shift the blame to us for not hiring a newer apparent warrants a bad review.
