Before the trip I've made a thorough online research; I wanted to have a great apartment for a fair price. And I've found it!
It was well-suited, cozy apartment in Nusiceva street, in the city quarter known as Terazije. The property was renting out by Basco, a notable accommodation agency in Belgrade. I found their offer online and picked this apartment as it had all I need, plus it was located on excellent place.
