We rented the appartment between four people. Very nice appartment. We didn't get the chance to meet the guests as they weren't in Vienna. Still, by email, they were very available and nice. The appartment is perfectly located in the 1st district of Vienna. Supermarket at 500 meters; metro and trams at 300 meters; airport shuttle bus at 500 meters. Close to Stephan's Dom and Mozart's house. We had a very nice stay the four of us.
