The apartment is okay, we would go back there.
Being there with a toddler, we actually were a bit disappointed about the fact we have found dirt and hair around: we talked about that to the person that helped us with the check-in.
After she proposed to call the cleanup service right away, we decided not to wait for the cleaners and accept the conditions (we cleaned up ourselves): our stay was so short (1.5 days) that organize/wait/leaver the apartment for cleanup would have impaired our plans.
Anyway, in case of a doubt: just move the beds (of all of the three rooms) on a side by 20cms (~10") and you'll understand if the cleanup service really worked for you.
