Benjamin of Tudela

From reading the descriptions of Constantinople and Bagdad by Benjamin of Tudela, I believe that he seems unbiased. For the description of Bagdad, he talks about it in an almost indifferent view. He points out things that would work for strategies to overtake the city and it’s merely facts. He talks about the caliph and his role, the wealth of the city, and the location of the city. The same for Constantinople, although he talks about the location, the amount of business in the city, the wealth, and explains the city in the same manner as how he explained Bagdad, which makes me believe that Benjamin of Tudela is a reliable source to read and use information from.
