We visited Kuelap last summer (July 2012) with Manuel but had several interactions with both Carlos and Manuel, and our experiences with them were great! Kuelap was beautiful and Manuel was very knowledgeable. He answered our questions well and explained many intricate features of the ruins, including the local plant life. I am not terribly fluent in Spanish, but I understood Manuel's Spanish very well. Carlos is a fluent English speaker. They have established a great agency, they are great guys, and they really love what they do as guides. I highly recommend using this agency when you are hoping to travel in Peru slightly off the beaten path. :)
