The bus station is really quite large because Cordoba is one of the main transportation hubs in the country. As bus stations go it is pretty good, with a few exceptions which i will note.
There are lockers, restaurants , ATM, Internet and I am told there is a tourist information office, which i didn't see personally. Relatively well organized and labelled I already had my ticket so all i had to do was sit in the restaurant and wait for my bus.
Well, not quite as simple as that. I had put my luggage in a locker earlier and gone off to see what i could of Cordoba since the bus didn't leave until the evening. The bus stations has hot showers, which is probably not a bad thing because bus trips in Argentina have a tendency to be VERY long so you dont want the person sitting next to you to have missed their shower. Anyway, I came back from sightseeing, opened the locker and got a change of clothes. Cordoba during the day is wicked hot (and it was only spring!). I went in to take a look, yes private shower stalls and all, still i decided against it since it just didn't look clean enough. One of the little pensions near the bus station let me take a shower (i had to pay a nominal fee)
One needs to buy a token called COSPEL from one of those news agent or tobacco shops before boarding the city buses of Cordoba.
So, if you are going to be out late or may end up in a place difficult to find such a place that sells 'cospeles', buy a few of them beforehand.
A one way ticket in December 2004 from Buenos Aires (Aeroparque) to Cordoba cost 233P/$79USD. This was with Aerolineas Argentina.
The airport in Cordoba is small and easy to get around in. There is a remis booth near the exit. From the airport to El Centro (Plaza San Martin), the cost was 17P/$5.76USD.
You can book a 3 hour city tour at the Solis y Nelson travel agency on 27 de Abril just off the plaza. Cost was about $15USD per person and the tour was in English.
A tour out into the countryside to see 2 old Jesuit estancias/missions was also $15.
A bus ticket (TAC) to Mendoza was 32P/$10.85USD. You can buy tickets at agencies located all over town.
We were told that TAC was a good bus company. However, it turned out to be a horrible trip. In Mendoza we were told that TAC used to be very good, but now it's very bad. I would never take it again given a choice.
Taxi from Plaza San Martin to bus station cost 4P/$1.35USD.
The best way to behave is with rent to car but it stops that it is necessary money and credit card, after that there are numerous tourist companies that you/they offer many tours that offer comfort and good prices. To be managed alone, the yellow cab costs around $0,50 the Km. Another chance you toasts through the urban communities with fixed price of $0,80 and the intercity ones that vary among $2,25 until the $5 dollars
Cordoba transportation system is cheap and easy. Taxis are usually less than 2 pesos (less than USD1.00) and there are many taxi companies.
