This is off the beaten track for most travelers to Argentina, but worth the detor. The city is on the river and has a wonderful creol feeling. It is really hot and super humid in the summer with mosquitos the size of small airplanes. Bring OFF if you go in the summer. You can visit some of the islands in the river where locals have asados on the weekend. There are also many nice bars and a busy nightlife. I think it is safer than BA and has a more small town feel eventhough it rivals Cordova for Argentinia's second largest city. The down side of this city is the traffic and smog. The busses put off such pollution that just walking along the street during the summer is a bummer. There is also a lot of noise pollution here.
