My girlfriend and I stayed at Brigitte's apartment for 3 days during Oktoberfest. It was a perfect home base! While the apartment is close to downtown Munich, it's even closer to the festival grounds (5 minutes walking!). While there was a small language barrier (to english), we had everything we needed! The room was huge and right next to the (shared) bathroom. If we came back to Munich, we'd definitely stay at Brigitte's again.
