Location, location, location! If your aim in Vienna is to hang out at the Opera or museums, this hotel is a fantastic choice. The 71 tram stops just a few doors down and is a direct route to Karlsplatz and the Opera. I never had to wait more than 7 minutes for a tram and could travel back easily and safely at night in about 10 minutes. I admit i didn't spend much time at the hotel, but it was perfectly fine and suited my needs.
