The house does not have a vacuum cleaner and It had not been vacuumed in a long time.
Even if the floors were cleaned with bleach or other disinfectant, the apartment was full of dust, hair... and other grey floating particles
After our complaints they came for an emergency clean but it was as superficial as the first one, which made the problem obvious.
I wouldn’t recommend it you have high hygiene standards, particularly in COVID times.
