As I have a nice flat in vienna for rent and would have also a garage to rent (as an option) for the guests, how I could manage this in my flat offert? Not any guest is coming with his car and is willing to pay for that service? Is there a possibility to offer optional services an Airbnb? Thanks for your inputs.
Hosts have the possibility to add extra services and asking for these costs through the Resolution Center (https://www.airbnb.com/resolutions).
When chosing this option, enter "extra service" and you can ask for payment for the use of the parking. Make sure that you explain this (and the cost) well in your description/house rules.
