The floor was absolutely disgusting. We took off our shoes and immediately felt how clammy the floor was. After 30 seconds walking around the apartment, our socks were black.
We traveled with our 1.5 year old and had to wipe down the whole entire house ourselves -- it looked and felt like it wasn't cleaned in probably weeks/months. We didn't feel comfortable letting her walk around and touching things in the apartment based on how dirty the floor was.
