I agree with travelover's opinion that it might be salvagable. Hard to tell from photo's. As he points out, the utilities (heat, light, electricity and toilet facilities) are the most important things and would be the most difficult and expensive to correct.
As to your question of whether or not it is "worth" fixing up, the answer that question is to compare how much you will spend fixing it up (include what ever your time is worth) compared to what it would cost to rent facilities that are already 'livable' times 2 or 3 years. I used the 2 or 3 year number based on my personal experience of changing work locations in that time frame. That number may be different fo you. To me. 'worth' is only a financial question. There may be other factors such as proximity to your home or the quality of the neighborhood.
