Hey there! :)
I am renting my cozy room for Oktoberfest. Is is around 20 qm, has a comfortable double bed and is part of a very friendly shared flat. We also have a nice kitchen and bathroom which you can use day and night. The bus leaves right in front of the house and it takes around 20mins to get to Theresienwiese/Oktoberfest from here. Two supermarkets are across the street and there is a key for the room and towels and bed sheets are included of course.
