I am renting my fully furnished room in our 4 room flat in München-Obergiesing. The room provides enough space for two persons. The bed (2m x 1.4m) is big enough for up to two persons and you will share the flat with my two (Hidden by Airbnb) who can give you a lot of tips and information about munich.
A big 20sqm kitchen, a huge TV and a lovely terrace are at your disposal. Besides that you can enjoy Pay-TV (Sport). WIFI is provided too.
And of course, an amazing city.
