Unfortunately, we were not happy with the conditions of the apartment. The mattresses of all beds where dirty due to prior guests. Talking to the host about this we received the answer that this is the way it is in a high frequenting apartment and that the bed covers should be fine in protecting us. We disagreed since we didn't want to test out what else is hiding in these mattresses.
Also, dishes where not really clean, the walls in the kitchen are dirty due to coffee or tea which hit the wall from prior stays, I assume.
The radiator in the bathroom was in a state that you would not put your towel on there - it was very dusty and had rust stains.
Overall we left the day we arrived and AirBnB refunded us the money. Over all the years we are using AirBnB this was the first time we moved out of an apartment due to unacceptable conditions.
