I recently stayed here for 5 nights (in town for a friends wedding).  The staff was extremely friendly and helpful.  The room - while basic - provided all the necessities (even had a flat screen!).  The floor I stayed on was apparently just remodeled.  The observation deck on top provided an incredible view of the strip at night.  Several economical dining options were also provided (in the mall area, as well as roxy's diner).  The only reason I give it three stars is that cigarette stench permeated the casino floor.  The smoke smell also seemed to travel through the walls into the room we were staying in.  Additionally, the hotel is located at the far end of the strip. This requires guests to either have to take a cab (cost prohibitive), rent a car (annoying), or take the deuce bus (painful).  All in all, I had a pleasant stay and recommend the Stratosphere for the budget traveler.
