Arrival ✈️


Citizens from EU or EEA countries do not require a visa to enter Poland. If you come from a non-EU/EEA country, you might need a visa to enter Poland.
Should you require a formal conference invitation to be issued a visa, please e-mail

Airport transit

Apart from taxi or Uber, there is also a public bus running between the airport and the city center. There are two-day time connections: numbers 208 and 252, and one night bus: 902. The bus stops are located near the passenger terminal.
You can buy the ticket in the ticket machine (there are two of them – one located in the arrival hall on the level 0, the other one at the bus stop. You will need an ‘agglomeration ticket.’ A single ticket costs 4 zloty).

You can also take a train to the city center. The Krakow Airport train station is located near the passenger terminal, at the rear of the multistory car park. A single ticket costs 9 zloty and can be purchased at the ticket machine in the passenger terminal, level 0 (cash payment or payment with credit/debit card), ticket machine at the train station (cash payment or payment with credit/debit card) or from the train conductor on board (cash payment only).

Accommodation & local transport 🚌

As Krakow is a lively and tourist-oriented city, there is plenty of options to choose from.
The conference is organized in Kazimierz, an old Jewish district in the city center, which is packed with hotels, hostels and AirBnB offers.
App.js will be held at the Qubus Hotel, so you can stay directly at the conference venue if you wish.

Good advice: when booking the accommodation, check if you can get to the conference venue easily. If you plan on using public transport, the nearest tram stop is ‘Plac Bohaterów Getta.’ You can also get there by train (you would need to go to Kraków Zabłocie station).

You can check your best route here:
(There is also ‘jakdojade’ mobile app available).
The 20-minute bus/tram ticket costs 2,80 zloty, 60-minute one is 5 zloty.
There are also Uber, Taxify and regular taxi services available.
Those who prefer riding on their own might make use of TrafiCar (pay per minute car rental).

You stay in the city center? Then why not take a stroll along the Vistula river and stretch your bones a bit before the conference! 🙂

Paying in Poland 💶

Even though Poland is a member state of the European Union, we use polish zloty, not euro (1 PLN is approx. 0.23 EUR and 0.26 USD).
It is possible to pay with euros in many places in Krakow, as the city is quite tourist-oriented, but remember that it is not a rule for every store/hotel/restaurant and that you might actually pay a higher price when you ask to have your bill converted to euros.

If you’re looking for a favorable exchange rate, visit one of the many exchange points in the city center (avoid the ones at the airport as the exchange rate there will be significantly worse).

Of course, most ATMs allow you to withdraw money, though you will probably be charged a service fee for the operation, so remember to check the rates and fees first.

Weather ☀️

April weather, rain and sunshine both together – that saying is quite true in Poland. April weather here tends to be very moody and bounces from rainy (sometimes even snowy!) to sunny and from 5 to 20 degrees Celsius. That is why we advise you to come prepared for all sorts of weather (and check the weather forecast before you pack).
For all those who are not water resistant – it wouldn’t hurt to pack an umbrella or a raincoat!

Safety/Person of contact 🚨

We hope your journey to App.js will go smoothly and you will encounter here nothing but great people and heaps of useful knowledge, but let’s keep some emergency numbers in mind. Just in case, all right? 🙂

  • 112 – general emergency number
  • 999 – ambulance
  • 998 – fire brigade
  • 997 – police

If there is something disturbing happening to you or you see something happening to anyone at the event venue, please reach out to our team members, volunteers or people at the help desk located at the entrance.

Sightseeing 🏰

Krakow is packed with monuments, historic sites, and museums and it would take many pages to list them all, so let us just give you a few ideas where to start your journey around Krakow.


Krakow’s main landmark, the Wawel Castle, has been a residence of many polish kings. Located atop the hill by the Vistula river, it is listed as a UNESCO World Heritage Site. Nowadays it serves as an art museum and is open to visitors daily, from 6 am to 7 pm.

Main Square

This medieval town square is a center piece of our city. It is filled with many historical landmarks, to name the most famous: the beautiful St. Mary’s Basilica, tiny Church of St. Wojciech, the Renaissance cloth hall Sukiennice (currently housing gift shops, restaurants and the National Gallery of Art) and the Town Hall Tower.

Wieliczka Salt Mine

Started operating in the 13th century, now is an official Polish Historic Monument. You can visit its many passageways, an underground lake, displays of historical salt-mining technology or the famous underground St. Kinga’s chapel.

Eating out 🍴

Krakow is practically packed with various food options, from street stalks and food trucks, through geeky bars to fancy restaurants. While some will enjoy a spontaneous walk in search of the perfect place for a beer or dinner, we know some others would prefer to make use of an insider tip, so, here are a few places we recommend:

Food track parks:


Sim cards and electricity 📱

The most popular cell networks in Poland are Orange, Play, Plus, and T-Mobile. You can buy sim cards in supermarkets, street kiosks, gas stations and in official company stores.
Remember, that registering with your passport or national ID card is mandatory when buying a SIM card.
Note: European Union introduced new roaming regulations in June 2017, which ended roaming charges across much of Europe, meaning you’ll usually pay no more for calls, texts and data in other EU countries than you would in the place of purchase.


Electricity tips:

  • Power sockets type E
  • Voltage 230 V
  • Frequency 50 Hz
