I'm working on a big project so I will need fast internet (>15 mbps).If it's close to the beach, it would be even better.
Check this one out in Santa Teresa/Playa Hermosahttp://skyloftcostarica.com/
It's run by a German guy and it has the most amazing views and great internet connection!
I already checked that place (which seems awesome btw) but I didn't find a cheap place to live nearby.So I'm still searching
