I stayed here from 08/03/15-08/7/15. I discovered bites all over my body on my last day. At first I thought they were just mosquito bites, but further investigation led me to confirm they were bed bug bites. Also bed bug bites appear days later after the initial bite and by the time I got home my entire body was bit up. I thought the hotel was nice, but definitely never staying there again.

Awful bedbug problem. Had multiple bites on multiple nights. Management ignored me then lied and said their eco lab checked the room. Finally was able to confirm bedbugs in the room.
