Quaint 1-bedroom apartment in Eureka connected to old Eureka home

By far the worst and strangest guest we have ever had. Despite clear directions that every other guest has followed with ease,Seth tried to enter the front door of the house and was upset when my cairn terriers did their job and notified me that someone was on the property. My dogs are docile and of course respond to dog commands and began to socialize with Seth’s dog which mad Seth, though not his dog who claimed was terrified by the enormity of my Toto-sized dogs. I pointed out that my dogs were no bigger than his dogs but he retorted “to him they are”. I put my dogs back in the house immediately and showed Seth the side entrance he was directed to use in the instructions. I later received a text complaint later that evening that my dogs were barking and causing his dog anxiety. I did not read the text for an hour or so after he sent it and did not respond because my dogs were quietly with my in the house and I did not want to disturb Seth at that hour. Seth is not welcome here again and I would warn other hosts that he is a problem. He seems to delight in finding things to complain about and is easily and strategically traumatized. He did no damage to the flat and his dog, who I pity, would be welcome to stay again.
