Really optimal transfer (calculate that from arequipa I had booked independently with cruz del sur and I can tell you without a doubt that this was much better in terms of seats, especially wider and more spacious). Superlative and extremely reclining seats that allow you to sleep really well. The company used seems to me to be Transzela. I recommend. As for the service of the operators, this is also really super, they picked me up at the hotel and took me to the terminal and got us the ticket. In practice, they loaded us on the bus without us having to think about anything. The only discordant note but really insignificant compared to everything: on the bus it was really hot:) ... In summary, I highly recommend it.
