Check the apartment, not just the town
Before booking, get the provider name and find out whether the connection belongs to the flat or is shared across the complex. Ask for a recent speed test from your intended workspace.

Two concrete fixed-line checks
Use A1 and Vivacom with the full street, building and entrance. For a new installation, agree the appointment, landlord permission, contract holder and fault contact. Coverage at the address does not establish an installed connection.

Home internet over a mobile network
A1 Net Box, Vivacom and Yettel home internet are alternatives where the chosen product is available. Check the exact service address, data and speed limits, equipment charges and minimum term. Address-bound home routers may need approval before a move to another rental.

A practical work-from-home test
Try a normal video call and file upload at the actual desk, then repeat during a busy evening. Test a cable connection if possible and save the fault contact. For family calls as well as work, this tells you more than the advertised maximum speed.

Build a backup you have actually tried
Test a phone hotspot inside the flat and keep enough data for interruptions. A second network is useful only if it works there. No year-round coworking desk in Sveti Vlas was verified for this guide; arrange a separate workspace directly if you need one.

Keep work arrangements separate from connectivity
For a short stay, a tested connection included in the rent may be simplest. For a new contract, compare the total cost, term and cancellation conditions. Remote-work permission, tax and insurance remain separate questions: see residence and taxes.
