Armin was extremely helpful with any questions that we had regarding the apartment and the city. Upon arrival he was very welcoming and made sure we knew about all of the best locations to eat, drink and do otherwise. The apartment was in a wonderful location, a short distance from the tram station. The apartment itself was very clean, had everything we needed and aesthetically pleasing, not to mention plenty of sleeping spaces! I would definately stay here again if I were to visit Vienna. It's a great choice.
