I live in an appartement in the south of Freiburg. There is quite a good connection to the center of the city. With the bicycle it takes 15min, to the tram station you walk 3min. Near the tram station are also some grocery stores located (Rewe, DM, Alnatura,...).
You will have the bedroom for yourselves. I will sleep in the living room, that works better for me.
If you want to make a booking, I expect that you are verified with your ID on Airbnb.
In the kitchen you are allowed to use any machines and tools, just make sure it is clean again after you used it. There are a stove with an oven, a food processor, a coffee machine, a dishwasher, a freezer, and 2 fridges of which you can use one for yourself.
