I'm going to take a bus trip to Cordoba in a few weeks so I went down to the Retiro bus station today to pick up some information about the trip. Good Lord! There's at least a dozen different bus companies that run buses to Cordoba. Any opinions about which ones are the best? Best for me means the fastest, most direct, most reliable bus. I'm willing to pay a bit more for the quickest trip. By the way, Cordoba looks a long way off on the map. About how long IS the trip?
