Teacher: You are given a review about a place. You need to provide a rating from "1 star" to "5 stars" for this place.
Teacher: Now, understand the problem? If you are still confused, see the following example:
Although I did enjoy the food here, I was completely unimpressed (and slightly annoyed) by the overpriced margaritas. I ordered a platinum which contained "fresh" juice. It tasted like it had sprite in it, so I thought surely she gave me the wrong one. It turns out that "fresh juice" is really margarita mix on tap from the same gun as the sprite. I asked for something fresh to replace the horrible margarita and received a rocks glass with just muddled lime and a salted rim. I'm not sure it contained any tequila. Horrible! It's not that hard to make a fresh margarita!
Solution: 2 stars
Reason: The writer has been annoyed in this place and has enjoyed the food. So, "2 stars" sounds reasonable for it.

Now, solve this instance: I am updating this review because I am VERY impressed with the new MGM "GRANDer" rooms. Now the rooms are on a comparable level with all of the 5 star hotels - Wynn, Venetian, etc.

The new bathrooms have a very sexy rectangle light which is amazing. The new beds and minifridge are clutch to any party. The new TV is significantly better than the old ones, and now there are audio/video plugs to throw a party.

The floor is significantly cleaner, the rooms are MUCH better than the old "classic" ones, and I am game to stay at MGM Grand every time!
