My boyfriend and I were searching for a reasonably-priced hotel in the center of the Strip, and Paris was exactly what we were hoping for. We stayed May 27-31, 2013.
The room itself was pretty standard - nothing nicer than a typical Comfort Inn really. We were on the 10th floor - I'm sure some of the upgraded rooms are nicer. The casino was nice, although nothing special compared to the rest of the Strip. There are lots of dining options in the hotel - the buffet was FABULOUS! There's also a creperie, a sandwich/pizza shop, convenience store, etc. The pool is really nice as well - really relaxed and wasn't very crowded during our stay.
I give the room itself 3 stars, and the overall experience of staying at the hotel 4 stars. The location simply cannot be beat - you're right in the middle of all the action on the Strip.
Note: Beware of the resort fee of $20/night. Unfortunately, all the Vegas hotels seem to charge some type of fee, so it's probably not avoidable.
