I have been coming to Costa Rica for many years I recommend the Sportsmens Lodge in Barrio Amon as both an excellent place to stay, and to have fun.
The Sportsmens is a hotel, restaurant, and bar setup that makes a good place to meet girls in San Jose.
Unlike some other places in San Jose it’s the kind of place where the owners are happy to let people have a good time and not get involved with the action so to speak.
The bottom line is you good a good deal at the Sportsmens and there isn’t any funny business on the side.
The Sportsmens Lodge is also a good place to start you day as it is the center of the action.
