We booked 3 nights and stayed 1, because of the cleanliness of the apartment. To be fair the host offered to clean it, but as many know with short stays it’s not easy to start worrying about that when on vacation. We opted to leave the apartment, and although the host mentioned they would not refund us any portion we understood and left anyways. Thankfully Airbnb has great policies in place and we were able to get a partial refund.
