It sits close to the city center — roughly 5–7 km east — and is usually reachable in 20–40 minutes by taxi or rideshare depending on traffic; fares can often range from modest local rates to higher amounts during peak times. Ground options include airport taxis, metered city cabs, and some hotel shuttles; public bus connections exist but can be slower and less frequent. Pros: very convenient for downtown access and multiple carrier choices; cons: facilities can be crowded and infrastructure may feel basic compared with larger international hubs.
