Good trip. The only inconvenience: the bus stopped only twice on a 20 hours trip and one of them was on a crowdy restaurant where, actually, we didn't get the time to eat. For the rest, ok!

Onibus muito desconfortável, velho, com cheiro de mofo. Era para chegarmos em Buenos Aires ás 11:30, chegamos ás 16:30.
