keep in mind the flat is located on the ground floor and is therefore quite dark and occasionally a moist smell is present. cleanliness was in general quite ok and is obviously depending on the other tenants, however the kitchen area might need a little more cleaning as well as the bathrooms. some parts of the apartment (like the towel rack in the bathroom) seem makeshift. after all, regarding the price you get what you paid for and especially the communication with the hosts is to be appreciated. keeping in mind the common areas are shared and not every individual might attach that much importance to cleanliness as you do, you will have good value for your money.
