"The one bedroom with fold out sofa room we stayed in had great facilities. It had a mini kitchen including fridge, microwave with convection function and there was a guest laundry too. You need to bring your phone to the laundry though as it's reserved and paid with an app.
A warning about the 90 min parking in front of the building, if you are unfamiliar with parking in Germany there is a thing called a parking wheel that you need to display on your dash. Use Google translate for any parking signs and inform yourself in regards to using the parking wheel. I think the people there just assume you know. From my experience asking the staff at the front desk about the parking won't prompt them to mention it. Paying the fine is a real pain to do from an Australian bank account."
