It doesn't seem like this apartment is owned by "Maria", but by a company called MintStay. The place is very, very small, specially the bathroom and the second room. Even though the apartment was cleaned, there were many spots in the bathroom that were dirty. We had a problem with the water of the shower/faucet leaking all over the floor. We think it was fixed, as we reported it, but we are not sure.
In short, this is an example of the many apartments in AirBnB that are not rented by their owners but by companies and offering a quality below standard.
