A7s, too early to play? Or played wrong?

[Bona]

The jury may be split on preflop I know some would fold it instantly, some would raise it if they play it, I probably should have folded it but I didn't.

The table is pretty loose and passive except for villain who is a tough and interesting player s/he is 36/9/2.63 after 61 hands. Looks at too many flops but seems to raise about the right number and has been tight and tough post flop.

Pretty standard or should I have called down in this pot against this player?
