What do the star ratings mean when you visit a hotel abroad?

I have found a hotel that i'd like to book but it only has two stars. I've been given mixed opinions, with some people saying the stars mean it's not a good hotel and others saying that the stars are just for the facilities the hotel has. The pictures look nice but obviously that can mean anything, I've seen a 4 star hotel that doesn't look as good and is more expensive. I can't seem to find any reviews on this hotel but we are going self catering so really we will probably have a couple of nights in and then just sleep there.

Any sensible answers would be helpful. Thanks x
