I'm planning to spend a few days in Vienna, in hostel, 2 person. I haven't started looking for hostel, so I have the question about the specific of finding hostel there:
- Do I need a reservation at all to get there in September? I was in Berlin in August, without reservation, and I've found free place in first of the hostels
- If I need, how much in advance I need to reserve? A week, a month?
- Is the prepaid necessary when making reservation, or I pay everything after arrival?
