You are placed in best location to explore majority of Belgrade by foot. If you need to go a bit more far away, we suggest to use public transport, since you have bus and tram stops almost in front of building. Public transport is not super-efficient and quick in Belgrade, but it is still much better than regular traffic-jams, especially in rush hours. Affordable options are also taxy services for which you can use applications; two of them are NaxiS taxi and Pink Taxi. We are sure, you have many own ideas and purposes of your staying here, however, if it fits you, we would suggest an easy walk by the river Sava bank, which can start just at nearby Kula Belgrade tower and can be stretched all the way to Kalemegdan park passing near popular Beton Hala bar area. We suggest also visiting some of Belgrade museums and beautiful parks, also do not forget to experience couple of restaurants with typical Serbian cousine and a bit of nightlife which Belgrade is known for.
