Bernies place is a lovely homey apartment in a good location in Vienna. Short tram ride to the zoo and short metro ride to the inner city. Loads of different eating places just 5 minutes of walk away. The apartment seems to be located in a quite busy area but it was still really quiet in the evenings even when we had all the windows open.
Bernie himself was really nice and provided us with a brand new fan since it was really hot while we were visiting. Would definitely come again :)
