The bus arrived 1 hour and 30 minutes later. The bathroom was dirty since the begining and the paper towel finished in the middle of the trip The bus just did 1 stop in 19 hours, and in a horrible restaurant in the middle of nothing, tbs bus driver was so rude on speaking, the wifi never worked inside the bus.
