We were in Montevideo for the day on a cruise ship and booked Jaime Gutierrez. Communication with him leading up to the tour was excellent with very quick replies to my emails. As arranged, he was waiting at the end of the pier with a sign with my name on it.
He was a great guide, spoke excellent English and was very passionate about his city. He was very knowledgeable, friendly and was certainly a lively and entertaining guide. He came with a driver, which meant he could concentrate more on explaining sites and things and was able to escort us when walking in the street.
I would highly recommend Jaime and would have no hesitation about booking his services again.
