There are already 1000+ reviews of Luxor, so I'll just sum it up.  You get what you pay for and you shouldn't pay much for the Luxor.  If they want more than $100/night, stay somewhere else.  The hotel is in need of a major refurb but it's fairly clean.  Biggest problem was that the rooms were far from the elevators and the elevators are slow.  Allow 15 minutes to get from your room to the casino.
