From my accommodation, it takes about 30-40 minutes to get to Oktoberfest. The bedroom is intended for 2 people. If you are more people, just ask. Air mattresses are available and I have already had 6 guests here for Oktoberfest. I don't have many rules. Feel at home, but we shouldn't bother the neighbors too much ;) Munich is a completely crazy city for Oktoberfest anyway. Welcome to Oktoberfest :)
