If you are looking for a clean, tidy and comfortable place you have to go to Tev place. He is very friendly and he replies immediately to your questions. The place is very near to public transport services and in around 20 minutes you reach the city center (also at night). If you need some suggestions Tev can give you excellent tips. Because of he has one of the best multicultural backgrounds I experienced, you can chat with Tev and discover a lot of original information. I will come back to Wien and I know already where I could stay. Thanks Tev!
