Studying abroad and living in San Telmo of Buenos Aires? Hi Argentina,

I'm a 20 year old American female college student potentially studying in Buenos Aires this fall. I'd be living in a student residence in San Telmo area. I was just wondering if y'all could tell me what it may be like to be an international student there! What San Telmo is like, what the student residences are like, nightlife, cost of food, if everyone will treat me like a tourist, etc.. I have a beginner's/moderate level of Spanish, so am not fluent, but hoping to learn more
