Hi there! :)
I am renting my 40 square meters apt. Ideally located- just 2 minutes from the main street Knez Mihailova and the famous Kalemegdan park. It's close to literally everything you would want to see (from historical places to cool bars) and it's the perfect spot from which you can explore Belgrade.
It'cute and cozy, fits 2 to 3 people and it's perfect for couples, people traveling for business and solo adventurers.
