we (two girls) are renting our flat the first weekend of Oktoberfest.
The flat is free from the 14th - 17th of september. You have the flat all to yourself and can use the kitchen and the bathroom as you want. You also have a balcony to enjoy the sun.
Restaurants, supermarkets and public transport connection is all very close. The metro is only three minutes away and it only takes 10 minutes to the city center and the main station and around 15 minutes to oktoberfest.
