My wife and I rented a sedan from Unirent car rental in Merida for about ten days in February,…read moredriving around the Yucatan. It was an excellent experience. Diego and his team were timely, reliable, efficient, cost-competitive, friendly and personified great service. They have my highest recommendation.
The good service started when I contacted them just a few days before our trip. At first, Diego said they did not have any sedans available. But a cancellation opened up a rental later that same day, he promptly emailed me to let me know.
Once we were in Merida, he brought the car to our hotel (the Hyatt), patiently and efficiently explained the details of the rental agreement and answered all of our questions without any rush. His English is not absolutely fluent, but certainly more than good enough for our purposes. The vehicle performed fine. Upon the completion of the trip, back at the Hyatt, he returned to the hotel to pick it up.
The only minor glitch we had was that the GPS system for the car didn't always work great, with a couple of problems along the way. (We thus used our Googlemaps GPS on our phones more often; it was better, though not perfect.) When I mentioned this to Diego, he took the charge off of our bill. I wasn't asking for this, but appreciated it nonetheless.
Two other minor matters were that the website does not seem to have an English option, though Google Translate works pretty well on it, and that it wasn't immediately clear whether a rental request using the online form was actually sent out to Unirent (though they replied promptly, either that day or the next, obviating that difficulty.) But really, these are trifling items. I wouldn't hesitate to rent from Unirent again, and wholeheartedly recommend the company.
