This anime is one of those that are focused in comedy most of the time and have little romance development.It can make you laugh a lot and you'll get attached for the characters,i don't think you'll hate any of them(well,maybe this doesn't count for Tamaki's grandma).
From my view points,there are a few negative point that made me give a 7 for this show.
1-This anime follow the "harém' settings,then the final is pretty open,but i think it should have a concrete ending,since it's obvious what couple would be formed.
2-I didn't get the flow of the episodes sometimes,it showed stories of the main characters but i didn't get a standard for it,then it seemed a bit randomic for me.
3-There's some unsolved stuff,things that has been told and abandoned and didn't have a conclusion at all.
Well,that's it,i usually give one minus of my rating for each negative point,but be considerate that this is just my humble opinion and you can watch and didn't see anything wrong.With this,i recomend this anime for you,since the jokes and comedy scenes made my laugh a lot like a good comedy should.
