The room was not updated, lamp shades were dirty, no microwave in room and spiders in bathroom. The bathroom has not been updated in years. The tile had another persons hair all over it.. room was shabby. Room was cold and damp and the air had been set in 61 degrees when we got there. The air conditioning made our allergies escalate.
