We had a great trip to Vienna and Roman's apartment was a big part of that! Roman was a great host! We had no problems finding the apartment or meeting up to get the keys. I had needed an iron since I was in town for a conferene, and Roman brought one by the next day. Location was perfect for us since I was attending a conference at the University and was only 10-15 min by foot. Rathaus is also nearby, as well as trams, buses and trains to get you farther away.
We were overall very happy with Roman and the apartment! It was definitely a steal for the price.
