I'm traveling to Germany in December. My budget is 1,000 euros. Housing will be free, because a friend of mine will let me stay at her house at no cost. I'm planning on partying around once a week, eating like an average student (I've heard döner kebab and Asian food is really cheap) and just getting to know the city's cultural spots such as museums, historic places, etc. Things that the 1,000 euros will be spent on:

• Bus tickets
• Groceries
• Alcohol (budget wine & beer is ok)
• A SIM card with internet access for 1 month
• Ticket to Bonn (and back to Berlin)
• Partying and nightlife

I've never been to Europe so I'm a bit lost, and asking my German friend isn't of much help because he doesn't live there as a tourist.

So, will 1,000 be enough for one month?
