The two ladies who helped us were terrific but there was a weird odor through out the entire hotel, the carpet through out was old torn up and dingy. Our room 315 tub was all chipped, the drain was gross and broken, the coffee pot was not cleaned or drained out, there was a cigarette burn in one of the blankets on the bed and I just think house keeping could do a more thorough cleaning in the rooms etc. The breakfast in the mornings are great and the lobby and setup is great just need quite a few more updates.
