I had a great stay at Armin's place. It was lovely, and very spacious. It was exactly as in the pictures, and it was a great location. It is just around the corner from the bus to the 1st district, and the train is only a few minutes walk away. Both train and bus gave quick access to the city center. Armin was a fantastic host. He was always quick to respond to messages and he was very helpful in giving directions to and from the airport and train station. He also gave helpful advice about how to get around Vienna. I highly recommend Armin's place to any others visiting Vienna!
