The Union is a clean and decent hotel near the center of Belgrade. It is located within a 5-minute walk of Trg Republike (Republic Square). It definitely has slightly better rooms than the typical formerly state-run hotels that dot the former Yugoslavia – rooms come with color TVs and cable, a minibar, and adequate lighting. Like a number of hotels in Belgrade, the Union boasts of their "recent" renovations at the end of the 1980s. Needless to say, the decade of turmoil and minimal maintenance have left some things that could stand to be improved, namely the bathrooms. The very basic plumbing system left our bathroom with the most pungent port-o-potty smell.
Overall, it was not a bad place to stay. The location was great and the price was not that bad, 60€ for a double. Check out this website for other hotel options in the Belgrade area: http://www.tob.co.yu/english/smestaj/hoteli/index.html
