Communication with Steffi worked out really well! She wasn't there herself since she was on holidays but arranged some friends to manage everything. We were warmly welcomed in Vienna, Steffis flat was ready for some visitors with even some notifications where we could find stuff. :)
The flat itself is nicely decorated with a lot of spiritual details with a very cute balcony and an awesome created toilet which you must have to see! :) The flat is perfect for a trip to Vienna and directly in a fancy district of Vienna near Naschmarkt. I can totally recommend going there! :)
