We are independent travelers, but not Spanish speaking, so we used TravelLocal's partners to arrange some tours, transportation and accommodations in Colombia that I was unable to do without Spanish. The guides for all four tours were excellent. We did the Tayronna National Park hike, tubing down Rio Don Diego, Exploration of Salento and Concora Valley and a day trip to a coffee finca in Codova and explored the village of Pijao. They also got us into Hukemeizi Hotel in Palomino when I could not. We enjoyed all our experiences. Our only complaint was our first driver was an hour late. The Colombian partner company was easy to work with and very responsive. I would definitely recommend them.
The guides were excellent. The vehicles and drivers were great except for what I mentioned below. Communication and response time was great.
Our transportation from Cartegena to Palamino was a bit of a disaster. The driver arrived over an hour late. We did not receive a call and when we tried calling all we got was a Spanish speaking recording. Our non Engligh speaking doorman was able to get a hold of someone at the agency. At Santa Marta we were transferred to another driver who's van ran out of gas and coasted into a gas station in Palamino.
Non Spanish speakers will have difficulty and using a travel agent to line up everything in advance would improve your experience.
