The floors were not clean when we got in the room. Our bare feet turned black within minutes. Past repairs were done poorly and the walls showed leaks form the A/c unit. Mattresses and pillows were very thin. Dishes were still wet and not dried properly by the cleaning staff. After the first night the a/c until stopped working and when I contacted the host I was informed that the maintenance staff was not answering the phone and that nothing could be done about it until the next morning. It was hot and we had to leave the unit and stay at a hotel for the remainder of our stay. Requested a refund for the remainder of our reservation. Will not stay at the Mariner again.
