Bike fit / correct riding position

Could i ride it? I know it would be a little big but could I still ride it ok, somewhat comfortably. I am on a tight budget build and just found an amazing frame for a great price, I don't want to pass on the opportunity.

It is only an amazing bargain if it will fit. Your height and frame size indicate a fundamental mismatch. You need to look again as I reckon 21in or 56cm, ,whichever way you wish to measure, will be right.
