Let's just say we take 1:10 train from Budapest Keleti P.
We get to Wien Meidling at 3:46 and Wien Westbahnhof at 4 PM. I think those are the east and west train stations, respectively.
Either will work. Westbahnhof looks a little less confusing via public transit. And we use that to get to Prague, so probably worth learning it.
Westbahnhof is at Europaplatz 1, 1150, Wien, Austria. The house is at Dampfschiffstrasse 12.
Their public transit website it nice. It tells you what direction, what line, and has pretty little maps.Here are the directions. We can get a 72-hour card for about $19. Obviously we are there for more than 72 hours.
Basically, take the U3 U-bahn line (orange) towards Simmering. Get off at Landstrabe Wien Mitte. You walk a little southeast towards Invalidenstrabe Street. Take the O tram north toward Praterstern S+U. It says to get off at Hintere Zollamtsstraße and walk, which we can. Franzenbrucke is two stops after that, might be closer. We just walk back across the bridge and hand a right, should be there.
