Pullman General Belgrano Montevideo Buenos Aires recent customer reviews

The bus attendant was a little more brisk/curt in his directions than I would like, especially when we went through immigrations. However, I take our interactions as a grain of salt due to the language barrier (I’m currently learning Spanish but not yet at his level of fluency). Overall, I was just pleased to finally be able to get some sleep on a bus ride! First one I was able to get over 5 hours of rest on :)

Cauvi staff in Montevideo were very helpful. But in Buenos Aires ticketshop staff were rude, unpleasant and didn’t help at all, in fact one lady of the staff asked for money to do her intended work.
