Stephan's apartment, in fact turned out to be my best stay in Vienna so far! I loved this cozy, clean and comfortable place, which is a few steps away from the trams to main locations and very near to U4 liner. I literally enjoyed my walks from the apartment to Augarten in the mornings and donaukanal in the evenings! Stephan was very particular about specificities of comfort for me as a guest and to my surprise, the house offered all amenities to cook (even with some masalas) and some books for interesting read! He was so kind to provide an extra bed for my friend and was always available for any clarifications. I would certainly recommend this apartment if you are visiting Vienna with either short term or long term plans.
