"For buses from Vienna to Bratislava you might want to try Eurolines buses (eurolines.com). I was just in Vienna a few weeks ago and it is very easy to get around. The subway system is very easy to use and most people seemed to speak English. I went to Bratislava for the afternoon one day. It was nice, though at least in my experience very few people spoke English. Then again, I was only there for a few hours.
