This is an erotic massage parlor located in the northern part of the often very dangerous Zona Roja (Red Zone or Red Light District). The structure looks just like a regular house except it is marked with the numbers 747. Considering that Costa Rica does not have mail delivery and there are no street addresses then it is obvious that these numbers discretely mark the house of sex. The sex here is cheap and ugly so come drunk and with a cool 15 bucks!
