21 year old girl looking for accommodation in San Telmo

Hi, I'm Caro from Germany and 21 years old. I'm doing an internship in La Plata for a few months and am looking for a private room in a shared flat to get to know new people. I'm always open to walking around and getting to know the city as well as going out for a drink, but I do also love just staying at home (maybe with a bottle of wine?) and watching movies or TV shows - all of which are much more fun with roomies. I would love to live in San Telmo or nearabouts. As I'm already in Buenos Aires it would be great to move in as soon as possible!
