Congenial means pleasant, and suited to your own taste. Congenial company, a congenial atmosphere, congenial work.
The suiting is the point — congenial means agreeable to you in particular, not agreeable in general. It is a mild and slightly formal compliment. Note congenital, which sounds similar and means present from birth; the two are unrelated.
