Cool things to do in Budapest?

Hey just got here and I'm interested in seeing what the city has to offer :) I enjoy arts, literature and more alternative things. I've already done some touristy stuff the last time I was here so now I'm more in it for the experience haha. In the evenings I'm looking forward to grabbing a drink and such. I'm staying for 4 days. If anyone wants to join me, they're welcome to. I'm a 19 year old girl and I study in Berlin.I would prefer hanging out with like minded people my age. But yeah, please recommend stuff to do. I'm on my way to the Fumei cemetery.
