Short version: we encountered numerous insects, still managed to sleep, and received a partial refund. The owner said he would get the pests removed soon.
Long version: soon after my family and I arrived at Liberty Inn in the evening, I saw two adult, probably German cockroaches on the walls. There were also numerous small insects on the walls that I couldn't identify, but which were probably not carpet beetles or bedbugs. Later I saw a couple of them in the rug so perhaps they were related to carpet beetles, but I wasn't as worried about them. My family was exhausted so we decided to stay put, since it was only one night and there weren't any signs of bedbugs. Later I saw a couple of younger cockroaches (see photos), which suggested a current infestation. I submitted an online review/note to the owner. He wrote back and asked me to stop by before leaving. We managed to sleep well after a long day, despite the bugs.
The next morning, the owner voluntarily gave me a partial refund and discounts on any future stays. He kindly assured me that the hotel took pests very seriously and that he hadn't known about the cockroaches before. He explained that there were monthly visits by a pest control service but that someone must have brought the insects with them when they visited. I hope that the concern he showed results in a strong attempt to stop the bug invasion(s) in its tracks, as soon as possible, for the sake of future travelers. Besides this the hotel was pretty ordinary.
