Danny Trejo -- 'Machete' Star Drops $550K on Mission Hills Party Pad

Danny Trejo must throw one helluva party -- 'cause he dropped $550K on a new pad in the San Fernando Valley ... and no joke, the place is set up for the ultimate blowout. Ok, maybe a little joke.

The "Machete" star's new 3,150 sq. ft. house features all the classics -- 4 bedrooms, 5 baths and a big backyard -- but that's really just where the fun begins.

Billiard room? Check. Pool and jacuzzi? Of course. Family room with its own wet bar? Yup, it's got one of those too.

And for the pièce de résistance (ok, maybe we overstate) -- the pad's got not one ... not two ... but THREE fireplaces -- just in case the 68-year-old actor wants to take each of his partygoers on a trip to s'mores country.
