Airport Transfer

Two public bus lines connect the Sofia Airport with the city centre – lines 84 and 384.

Bus line N84 from Sofia Airport Terminal 2 via Terminal 1 to General Gurko Str offers convenient connections to the city metro line at the stops on Orlov most bridge and Sofia University “St. Kliment Ohridski” in the city heart. The bus ride from the airport takes between 30 and 40 minutes.

Bus line N384 from Sofia Airport to the Mladost district is the fastest way to reach the metro. The bus stops at Terminal 1 and Terminal 2 and after several intermediate stops terminates at the stop near to metrostation Mladost 1. You will need a separate ticket to use the use the metro to get to the city centre from there.

Public transport tickets can be purchased from the vending machine placed at Terminal 1, at the newspapers kiosks in the public areas of Terminal 1 and Terminal 2. You are supposed to have a ticket when you enter in the bus, you can normally buy bus ticket also from the bus driver.
Tickets cost BGN 1.00 / 0.5 EUR. A piece of baggage sized larger than 60 cm x 60 cm x 40 cm is charged by a separate ticket. A ticket is valid only punched in the device inside the bus.
The public transport operates from 5AM to about 12AM.

By Taxi
For your comfort and safety, we recommend that you take a taxi at the designated taxi stands in front of the western exits from Arrivals at Terminal 1 and Terminal 2. Alternatively, you could request a taxi at the desks of the taxi companies, which are located in the Arrival halls of the both terminals. Most taxi drivers don’t speak English, but they should find the hotel if you show them the address. A normal price, generally speaking, from airport to city center should be around 10-12 BGN, not too much above that. A good company is OK Supertrans, the problem is fake taxies use similar names and appearance as OK supertrance, so always check the price printed on the front window and side windows of the car – it should be normaly between 70 stotinki and 1.50 BGN. Not too much more than that. Another good company are Green Taxi, but the need to be ordered via mobile phone (00359 878 810 810).
