When is the perfect time to go to Greece?

I want to know when is the perfect time to go to Greece?

Well, I am not sure when is the perfect time, as I went in summer, which is slightly hot. I guess Autumn or spring would be good. I just came back from Greece last week. Santorini is absolutely beautiful! I love Athens too.

Are there any good plans for me? No idea what is good for you as everyone has different taste in travelling. I was on a cruise, which is highly recommended, so I went to a few of the Greek islands.
