If you are heading from Sosua then this is my easiest way. Just drive as if you are heading to Tropical, this is by going straight through the round-about, past the court house, keep going past the police station, and right after the station this is where you need to divert to the left. NOW, when you are a block away from the left turn to Tropical, where there is a small park, you turn right onto the street just at the beginning of the park, one block down and a left turn you are at the back entrance to La Sirena. You will easily see it at this point.
Hope these directions make sense, they should if you've ever driven this way to Tropical. Sorry, I never remember street names.
