I travel to Eureka once a month and usually stay at this Motel 6, as I travel with my dog. This Motel 6 is a bit dated, but much less then the other Motels in town. Before I started staying here I use to stay at the Quality inn. For about $30 more a night, and all I got was a crappy breakfast there. This Motel 6 is very clean, and the desk people were very friendly and helpful with providing me places to walk my dog.
Another reason I stay at this motel when I travel to Eureka is that this Motel has security. Eureka is full of homeless crack heads wondering around. Doesn't matter if you stay at a 5 star hotel or this motel 6. If you are in Eureka, you will eventually be confronted by a crack head. At least this Motel cares enough to try and do something about the crime, and protect their guest.
So yeah, this property is run down a bit, and has the occasional miscreant wondering around. It's by far though the best you're going to find in the lower price range in the hole that is Eureka.
