Seinfeld Never Went in George's Apartment

I'm 98% sure on this, but I think Jerry never set foot in George's apartment.  George always came over to his place.  What an asshole, he's the guy that always makes you drive over, never wants to do anything outside where he is.  He went to George's house with his parents, I don't think we ever saw George's older place before he moved back home, did we?  Is this what that Curb Episode was about?  The one where George and Larry can't decide whose office to go to.  That may have been a reference to this, since George always obliged to go over to Jerry's in the show it would appear.   

Speaking of which, did he ever go into Elaine's newer apartment, not her old one with the roommate, the one with the rattan piece?  Wait, yes he did before the Devils game.  But I think I'm right on the George's apartment thing.
