This was an awesome stay. First, Andreas and Silvia are the most kind, gracious and cool hosts that you could find. I got a sense that they really enjoy having guests from all over the world and are not just doing this for money. It turns out that we share a lot of common interests. I had a blast chatting with them, especially the times they treated me to special meals. Second, their apartment is probably one of the coolest in Vienna. Andreas is an architect and he designed a lot of the stuff himself. The space is modern minimalist with very few things but everything is high quality and stylish. The guest room is cozy and bright with a spectacular view of old Vienna through the windows. Finally, the location could not have been better. It is a 2 minute walk from the Stephansdom church and basically a few minutes from everything. The best part is that it is in a small quiet alley even though it is 20 m away from the busiest tourist area in the city. I would definitely stay here if and when I come back to Vienna.
