First walking in to the unit everything looked great. After a long day of flying we decide to take showers. I get in the shower it started off hot but then got cold within 5 minutes. We contacted the emergency number that was left in case of any problems but didn't get an answer. As we were getting ready to lay down we noticed the blanket had stains on it and the sheets were very hairy (possibly pet hair). We didn't see any other clean sheets to use so we had to throw the sheets and blanket in the washer to get us through the night. I messaged the owner on airbnb and the next morning he said he would send someone out. The lady came with fresh sheets she was unaware of the hot water issue. She tried to turn up the water heater but that didn't help she suggested we just take staggered showers so the rest of the trip we were taking quick 5 minute showers. We never got a follow-up response from the owner or an apology for the issues we were experiencing.
