In general, it’s safe to use taxis in Budapest since they work with a fixed price table (the base price is 700 HUF, the distance-based fare is 300 HUF/ per kilometer, the waiting fee (75 HUF/min).
All official taxis are yellow and you can spot the taxi company’s logo on the top of the car and on the door.
NEVER use a taxi with a Freelancer sign indicated in black color on the car. These taxis don’t belong to any of the official taxi companies and they are not reliable. They might charge you 2-5 times more than the usual rate.
