We traveled to Costa Rica in March, 2014. There were two families...a total of 4 adults and 4 children. Abner was funny, friendly, helpful, and knowledgeable! We felt comfortable with him the minute we met him. He took us everywhere we wanted to go and had some great ideas of other places to visit. He helped the kids learn some Spanish, as well as improving the adults' Spanish. He helped us out in changing hotels since we booked the wrong one. I would hire Abner again without reservation!
