Conditions of train ticket between Vienna and Bratislava

I'm planning a trip to Vienna, and I'd like to visit also Bratislava. I've found a page with prices of train tickets: http://bratislava-slovakia.eu/travel/vienna-bratislava/vienna-train, however, the information presented there is not very clear to me:

What is 'Return ticket "Wien Ticket"'? Is it a ticket in one direction only, or back-and-forth ticket?
What is 'Ticket valid 1 week'? If I buy such ticket, it mean I can travel back and forth the whole week as often as I want? It could be an option to find accommodation in Vienna or Bratislava and simply travel to the other city each day, instead of moving from one hostel to another.
Is this a single person ticket, or it enables to take some 'belonging' such as other person, children, bicycle?
