There are a few other suburbs near San Jose that may be worth checking out – one being Heredia.
I didn’t check the area out much, but I’ve heard good things.
While I wasn't a huge fan, I have met some men who loved the country. Tico men are smaller and I think my upper body size was a bit of a deterrent for them.
A small European guy I knew got jacked at an ATM for $500.
I did hear some great things about Tamarindo, which is a beach town on the Pacific coast of Costa Rica with good surf and nightlife, but I didn’t check it out. Costa Rica is great for nature, good for beaches, and can be a lot of fun - but it isn’t good for a budget traveler looking to bang a number of hot chicks.
