It has a lot of potential if the staff, AC or central/fan system worked, and better amenities. the room was large and dirty, set up like a party room. So much more can be done to the interior decor to one account for the cost and the location, even if it is just to sleep. The shower area was way too large with some much open space can fit the offense of a football team in it, but the tub (shower/tub in one) was nothing fancy nor large. Very little hanging and storage space for the size of the room but it was just a one night stay.
