The price of the lodgement including full meal is u$ 190 from Sunday 8th. afternoon to Saturday 14 th. in the morning. The extra charge for single room is u$ 5 per night.


To get to Córdoba from abroad, you can fly with Varig (a brazilian airline), which has direct (daily) flights from Sao Paulo or Río de Janeiro to Córdoba. You can also get to Córdoba through Buenos Aires; in this case you arrive to the International Airport of  Ezeiza, then you can take a bus (Compañía Manuel Tienda de León) to the home-flights airport (Aeroparque  Jorge Newbery ).  From the home-flights airport there are flights to Córdoba each hour.

The system  Amadeus provides information about the times of the flights.

There will be two minibuses to take people from the Córdoba Airport to the hotel on Sunday 8th.: one in the morning (around 10) and one in the afternoon (around 15). The price of the minibus is u$ 8 per person (approximately, to be confirmed in this page).

It is important for us to know your time of arrival if you want to go in any of these minibuses.

If you are not going to travel in one of the minibuses, then you can either

Argentine current money is the peso.The value of one peso is one US dolar.  Taxis, restaurants, etc., can usually be paid with US dolars instead of pesos. We will organize change of money (only u$ to pesos) on Monday morning.

August is still winter in Argentina. The weather in Córdoba is still cool, specially at the evening. We suggest to bring appropiate clothes. The hotel has heating.

The city of  Córdoba has 1.300.000 inhabitants. The Universidad Nacional de Córdoba is more than 400 years old.
