After a 2-hour drive with our toddler and dog, we arrived to find no entry instructions, nonfunctioning A/C despite visible vents and a thermostat (not disclosed in the listing), and, worst of all, what appeared to be an active ant infestation. Within 15 minutes, we'd found approximately 50–100 ants across the bathroom floors and additional ants in multiple areas of the living room. This was far more than a few stray insects.The host told us he was out of town and couldn't address the ants until the next day. We weren't comfortable staying under those conditions with a young child and dog. Turning around and driving home was a miserable decision, not one we made lightly. The host agreed to handle the refund.After we left, he questioned whether the ants were even there, despite my sending video evidence. He acknowledged seeing a few himself, then pointed to a video from the following morning showing none, as though that disproved what we'd documented.He now refuses a full refund, telling me, "I think you overreacted for something that could have been easily resolved. We will have to fight this out."We reported the problem immediately and left only because he couldn't address it that day. The ants were bad enough; being dismissed and challenged afterward was worse. I would never book with this host again.
