Replying to Anyone been to Belgrade???

I was wondering how many of the NS community has been to Belgrade. I am going there this Friday, and I would like to know how safe the city is? and what is worth going to see? I know after Kosovo became independent there was a lot of hate towards foreigners, and this is still a major issue in Serbia. If anybody could give me some information on Belgrade or the situation in Serbia in general it be greatly appreciated. Hope to receive some posts.
