House was 52 degrees Fahrenheit downstairs. Vents blew cold air. Host Courtney stated she would send a hvac tech. None showed. I messaged again and she stated it looked like temp going up. I immediately messaged that it had not started to heat, and did not change. I phoned the direct number for host that VRBO gave me. No return calls. She stopped messaging at 9pm. Unacceptable and unprofessional. The temp outside was 23. She did not offer to send electric heaters or for another place to stay for the night. It ended up taking 24 hrs to heat up to set temp on thermostat. Courtney stated that the furnace had run for four straight days non-stop, yet never had it serviced or notified us prior to our trip so we could have reserved a hotel room.Host was very quick to answer questions until there was an issue with the furnace not heating. Then she ghosted me until the next day. We checked in at 5pm. Slept in coats, gloves,scarves,and shoes underneath the blankets. At 9pm the temp inside had not risen 1 degree Fahrenheit.Plans of a relaxing evening was a disaster. We could not utilize the hot tub due to the frigid indoor conditions.The “fireplace” was holographic,little to no heat.Cleanliness was superficial. A clipped toenail was found in front of the sofa. A pill was found on the main floor bedroom that was identified as glipiside,a diabetic med that would be detrimental to a child if ingested. Balled up cobwebs hung from beams in main bedroom. Dust under end tables and bed.
