The place we actually rented was fine, however it was not ready upon our arrival. We ended up staying in a downgraded version of the property for half of our stay.
This other property that he supplied was much smaller, had only double beds, only one bathroom with a tiny square shower, an unusable dirty stove and heat being controlled by the owner.
Our advice is if the place you actually rent from him is not available, don't accept something else. One night may turn into two or more and he will refuse any type of refund. And Aircover won't help because it's not the advertised property. Good luck.
