Wombats was great in Vienna at the Naschmarkt. As most people have said, it is close to nearly everything. Metro 2 minutes from the door, the market right at your door, and the city centre is a nice easy walk. Plenty of good places to eat as well, and Vienna is just an awesome city! The bar was good, plenty of common room area, they didn't have my booking in the system for whatever reason, but it was sorted out. It's a huge hostel, but generally everyone seemed pretty respectful and the hallways/doors seem to block a lot of the noise.
