Helena's place is amazing and well thought-out - the couch/bed is definitely the main feature. The layout is used optimally to get the most out of it. We appreciated the presence of bicycles, and the ability to put away our car close by. Helena's husband Pero gave us a great introduction and a nice overview of the best Vienna has to offer with a few personal touches as well. We can definitely recommend their place for anyone staying in Vienna for any duration!
