I may have to take an unplanned solo trip to Graz where I will be staying in a Youth Hostel. I'm very nervous and a little scared about it and was wondering if anybody recommends doing this. I'm a young American woman and I don't speak German. It would be for two nights and 3 days (only one full day). Is there enough to do in Graz? Is it safe? Would it be safe to meet people in the Hostel to travel with?
