First, the location is a plus. It is right next door to the LV Convention Center, which means you can walk to a show. It is also off-strip without the hassle and constant barrage of a strip hotel. You can get to the Strip via a cab $6-$10, a 1/4 mile walk to the monorail via the Convention Center station, or it you have a cab-drive and park free in any of the hotel parking garages.
Also, there is plenty of Dining choices on Paradise Road nearby including PF Chang's, Lawry's, Bahama Breeze, Hofbrauhaus, and Del Frisco's.
Second, the rooms are nice (and excellent compared to what you may end up with on the Strip.) Third, the amenities are worthwhile. From a nice lobby and pool to your eating choices--Cafe, Bar/Grill and Upscale Steakhouse, you have what you need at the Renaissance.
Finally, the staff is friendly and values you as a guest.
