Taxis from reputable companies in Niš are generally clean and reliable. They are quite expensive for Serbia; a typical fare across town might be €3 (300 dinars) for a four Km journey. A tip is not required, but is appreciated. Pets are transported with the driver’s consent. You can ask the taxi driver about the hotels, restaurants, or indeed anything you would like to know about the city or local politics. Most drivers are smokers, but you can request a non-smoking vehicle or simply ask the driver to extinguish the cigarette.
Avoid taxis that do not belong to any taxi company (their roof signs display only ‘taxi’ without stating a company name), who usually hang around the Railway station and accost travellers. They will overcharge you either by negotiating an exorbitant fare or using a fast meter. Stick to the trusted firms.
