Useful Information


Getting to Sofia

By plane

Sofia airport is located 10 km from the center of Sofia city. It has two terminals. Terminal 1 serves mainly low-cost and charter airlines. Terminal 2 is significantly bigger and currently serves many companies and Ryanair flights as well. There is a white free shuttle bus running every 30 minutes between the two terminals. There are a few kilometers between the two terminals and they are not in a walking distance. Public bus line 84 travels to both terminals. Allow 30 to 40 minutes to reach the city center depending on traffic.

Getting to the hotel

Grand Hotel Millennium Sofia is located 11,5 kilometers away from Sofia International Airport. The hotel can be easily reached using the Sofia Metro. Sofia Airport station is located next to Terminal 2. Make a switch at “Serdika station” to Line 2 for one more stop to National Palace of Culture (NDK) station. Make sure you check carefully the terminal that you are arriving at or departing from.

The metro operates with separate tickets that are not valid for other modes of public transportation. Tickets are only sold at the metro stations at ticket machines or at manned ticket booths (again cash-only). The cost of this transportation is 1.60 Lev. The tickets are only valid up to 30 min after purchase.

A taxi from the Sofia airport can be ordered as well. There is only one company that is allowed to service the airport (OK Supertrans). We recommend that you do not use taxi services offered outside the office of the taxi operator or in front of the terminal to avoid overcharge.


Participants can order individual transfers from Sofia airport (bus/railway station) to their hotel or v.v. to CME Ltd. The price per person for one direction is 30 Euro. On arrival at Sofia airport, a member of the organising team with a sign with conference name will welcome participants. The organising team will take care of all transfer arrangements from the airport (bus/railway station) to the hotel. On arrival and during the first day of the event, delegates will be asked to confirm their departure times. Transportation will be organised from the hotel to the airport (bus/railway station) for those guests who have booked and paid the transfer individually.

Transfer(s) can be booked through the online registration form.


Re-open EU platform (or the App) provides information on the various national restrictions in place, including on quarantine and testing requirements for travellers and mobile contact tracing and warning apps across Europe. The information is updated frequently and available in 24 languages. This should help you plan your travel in Europe, while staying safe and healthy.


Bulgaria has the European Union’s Common Visa Policy as a member country accepting European citizens freely. All non-EU citizens are required to have a passport to enter the EU with the appropriate visas. Conference attendees are personally responsible for making their own visa arrangements. You can find out more about visas at

However, if you need an invitation letter, please send a mail to


The national currency is the Bulgarian Lev. Bank notes of the following denominations are in circulation: 5, 10, 20, 50, 100 Levs. 1 Euro = 1,95583 BGN.

There are foreign exchange offices and ATMs everywhere in the city. It’s always prudent to carry a little cash, however, in case you can’t find an ATM or bank office nearby. You can always change cash at the hotel, though the commission will be higher.

Make sure you have enough of the national currency when you plan to visit local markets and shops.


When a gratuity is not included in your bill, which is usually the case, 10% is customary. If service is outstanding, you could go as high as 15%. With taxi drivers, you usually just round up the sum if you have been happy with the ride or for the sake of convenience.


The climate in Bulgaria is moderate continental with beautiful blooming spring, dry and hot summer, long and pleasant autumn, and mild winter with lots of opportunity for skiing.

The weather at the middle of September is warm and sunny with daily temperature of around 22 ºC, which is very pleasant both for work and leisure.

You may check current weather in Sofia HERE.


Summer time: GMT + 3 hrs. (April through October)

Bulgaria uses CEE 7/4 (German “Schuko”) power plugs and sockets.
