从维也纳机场怎么到Erlachgasse Housenumber 63 Top 11 维

这里有一份英文的说明，但我搞不清楚具体要坐什么车，尤其是乘坐完S7以后，要出去地铁，到外面去坐电车？求助在维也纳生活的童鞋指导。
Take the escalator on the left towards the S7 train and purchase a ticket from the automatic machine at the foot of the escalator between the tracks. Go 5 stops to Geißelbergstraße. Get off and look for the stairs or elevator to street level towards the back of the train from the direction you came from. Cross over the street and look for the sign for Tram 6 in direction Burggasse. Ride about eight (?) minutes (3 stops) to Gellertplatz (it is a traffic circle). Exit the tram and walk right from the circle on Gellertgasse two blocks to Erlachgasse. You will see the LIDL grocery store on the far corner. Turn left on Erlachgass and my door is just on the left, number 63 , buzzer number 11 another possibility the "airbordbus" to Vienna - Schwedenplatz - than metro U1 to Keplerplatz - exit Viktor Adlerplatz, at "Tchibo" turn to the left side, it's the Erlachgasse, straight ahead 5 min
