it said online $50 for a room so i call to make a reservation, the lady tells me it will be $78 i said it was fine. Then she pretends her computer crashes then she says it will be $50. I get to the room it is extremely dirty mirrors arent clean carpet everything you can see has not been wiped down. I leave the next day with a bill of $78.
