Thank you so much Helena for the hospitality!
The enormous bed where you can twist 360 degrees in your sleep was impressive enough, but the Star Wars/Trek/TNMT/GoT/Avengers fresco totally blew me away. Also, there were more than 10 beers in the fridge which was the best welcome I've ever had. She also helped me with all the tips and tricks about the city.
Next time I'm in Vienna, I'm coming back for sure!
