Apartments commonly come fully furnished, so a nomad can move in with furniture, appliances and sometimes kitchenware included
Commission-free renting is realistic by dealing directly with owners or using no-fee agencies, and deposits are modest (typically one to two months' rent)
Emergency medical care is available to any foreigner during a temporary stay; dial 194 for an ambulance (the EU-wide 112 also works in Serbia and routes ambulance calls to 194).
Legally employed foreigners registered through the Central Registry (CROSO) are enrolled in RFZO (mandatory social insurance) from their first day of lawful employment, giving access to public healthcare — but they must hold private insurance for the period before employment begins.

Watch out for

The White Card registration is mandatory within 24 hours and is typically required before a residence permit can be applied for — confirm in the lease that the landlord will register you (or register yourself at the police station)
Insist on a written, ideally bilingual (Serbian + English) lease: without one, the default eviction notice period is only 8 days and deposit/utility terms are hard to enforce
A short-stay nomad who is not employed in Serbia generally cannot use public care for free — temporary-residence applicants must hold health insurance covering their whole intended stay, and non-employed people only get public entitlement once contributions are paid.
Citizens of countries with no health-insurance agreement with Serbia must pay for urgent medical services and seek reimbursement later from their home insurer.
