Prior to arrival, I requested an early check in, it was not available, but the parking space was available. My wife and I dropped our luggage off in the front hall closet and we headed to Summerfest around 2pm. The host contacted us and he let us know the cleaning crew would be done by 3pm if we wanted to get in an hour before the official check-in time. I told Mark that we had already headed to the Fest. We stayed at the Fest until 11:30pm, tired and ready for bed. I brushed my teeth then headed to the bedroom. As I moved the night stand to access the electrical outlet to plug in my phone charger, I disturbed several bugs, probably cockroaches, they scurried in all directions. I must have made a noise, because my wife ran towards the bedroom and asked if I had seen bugs. I tried to get my phone off of the charger and take pictures of the bugs, but I only captured an image of one insect.As she approached the room, an insect was climbing the wall. I immediately contacted the host, at midnight, after no response to resolve the issue. I decided to drive two hours home.We used the bathroom and walked into the bedroom. We were in the unit for about 20 minutes. I requested a full refund, I was denied because my photos were not clear enough and I did not count the number of insects. The bugs were not common boxelders, lady bugs, ants nor house flies. I was told that it was my choice to leave and I did not give the host time to remedy the issue. Mark, the host issued a 100 refund.
