Posada Mariposa is a lovely little inexpensive place in Playa that I stayed on the way home from a trip in Dec. It's not by the bus station but there are cabs all over and they're cheap. It is a couple blocks from a lovely beach. It also is on a street with yummy restaurants, plenty of ATMs, and an internet cafe with phones. There are also some gift shops there. Little traffic. I enjoyed it.
