Where is Envy nightclub in Athens?

Travel Info
I've heard Envy is a hotspot to go out at in Athens. Is that true? What kind of music do they play? More importantly where is it exactly in Athens? I've looked at several different websites and the address is in Kifissa area on Diliganni Street. I tried to find it on a detailed map of Athens but had no luck. Where is it in relation to Syntagma Square?
