For airbnb I can offer this spacey room with double bed plus another smaller sofa bed, with piano (If anyone plays!), placed in a very calm part of the city.
By foot, you are in the city center in 10 minutes, and next to the house you can use a public transportation that goes from the airport and back. You have 24h open smaller grocery store, and two big ones. Also, two bakeries in front of the house.
The neighborhood is typical Serbian, alive and awaken.
