Hello Hridya! I like your article and it's great to hear that you like Belgrade and Serbia in general. Serbia is such a beautiful country and has really a lot to offer. If by any chance you come back, I would recommend you to have a nice tour at the countryside, outside of the Belgrade. There are many interesting locations where you can have a great time discovering some extraordinary sites! Remarkable viewpoints, waterfalls, caves, archaeological sites, hiking through picturesque nature, savouring Serbian cuisine are just some of the reasons why you should not miss it! Here is more info on the matter http://balkanway.com/useful-serbian-tips-and-facts. Cheers!
