With the current exchange rate, you are looking at over $5000 pesos per month, which is considered a good salary for an Argentine. However, if you are paying rent in dollars, like steveinbsas said you wont have a load of money left over to play with each month. However if you can find a share for let's say $500 U$D or less, you could have about $3,000 pesos per month to spend on food, entertainment, etc. With $3,000 pesos per month you could certainly enjoy yourself here, as long as you are not going out to eat in Puerto Madero every night. There are many people here that earn less than $3,000 pesos per month here, and they have to pay rent, utilities, food, entertainment, etc. out of that. Again it all depends on the type of lifestyle you want to have here in Buenos Aires.
