Practical Information

Room location & RegistrationThe rooms are located within the main building of KTH at the addresses

• D1, Lindstedtsvagen 17 (6th floor)

• D2, Lindstedtsvagen 5 (3rd floor)



One can easily find them in the figures 4-7 or by typing “KTH D1”, “KTH D2”, ... in Google, where apath from your actual position and the room location will be highlighted.

A registration desk will be present at the entrance of the D building (Lindstedtsvagen 5) during themornings of 15th and 16th between 08:00 and 11:00 for the registration of the conference participants.

Social EventsLunches and coffee breaks are planned during the conference according to the time plan. Lunches willbe served at the “Q Restaurang” located at Osquldas vagen 4, 100 44 Stockholm (see map in figure 1).

Furthermore, two social events are planned:

• Tuesday, the 16th of June (from 18:00 until 20:00): The Conference reception at the Stock-holm City Hall (Stadshuset), at the address Hantverkargatan 1 (5 minutes walk distance fromT-Centralen, see map in figure 2).

• Wednesday, the 17th of June (from 19:00 until 23:00): The Conference Dinner in the StrommaKanalbolaget boat (M/S Gustafsberg VII) at the Pier 8, Nybrokajen. (10 minutes walk fromOstermalmstorg subway stop, see map in figure 3)

Public transportation is available to reach both locations.

Meeting roomThe room D32 is also available for the conference participants for discussions and meetings.

How to get to the conference venue from the airport?Stockholm is situated at the heart of Scandinavia, and most of Europe is reachable within three hours.There are 4 international airports in Stockholm.

1. Stockholm-Arlanda Airport - www.arlanda.se. Key hub for flights to major destinations in Europeas well as the rest of the world. It is situated 40km (25mi) north of the city. The fastest way togo to the city center is the Arlanda express train which takes you from Arlanda Airport to thecity center in 20 minutes (with trains every 15 minutes for most of the day). There is also a coachservice departing every 10-15 minutes between Arlanda Airport and the City Terminal (locatednext to the Central Station). The bus travel time is approximately 35-40 minutes.

2. Stockholm-Bromma Airport - www.brommaairport.se. Stockholm-Bromma Airport is a small city-airport offering both scheduled (mainly domestic) and charter flights. It is located conveniently closeto central Stockholm (20 minutes by bus).

3. Stockholm-Skavsta Airport - www.skavsta.se. Stockholm Skavsta Airport is located 100 km southwest of central Stockholm. The airport is a hub for Ryanair and other low cost airlines and offersdirect flights to several destinations in Europe (80 minutes by bus from central Stockholm).

4. Stockholm-Vasteras Airport - www.vst.nu. Stockholm Vasteras Airport is located 100 km northwest of central Stockholm. The airport is served chiefly by the low-fare airline Ryanair.

All above airports offer coach services with departures timed with arrivals and departures at the airports.The travel time is 15-20 minutes (from Bromma), 80 minutes (from Skavsta) and 75 minutes (fromVasteras).

Public transportThe public transportation system in Stockholm is punctual and efficient so that visitors can quickly travelbetween different locations. The conference participants can find details about the transportation in thewebsite www.sl.se/en. A single-journey ticket can be bought for 36 SEK (valid within 1 hour), but werecommend to buy the SL cards (those can be found in many shops, like Pressbyran, 7-eleven, or the SLoffices) and to charge them according to your plans. Each used ticket will cost 25 SEK. It is also possibleto buy tickets for 1, 3 or 7 days with the cost of 115 SEK, 230 SEK and 300 SEK, respectively (pleasekeep in mind that the ticket starts from the day of the purchase).

TaxiThere are many taxi companies to choose from in Stockholm. Approved taxis with metered fares alwaysbear yellow number plates. Credit cards are readily accepted. Taxi prices are not regulated in Sweden;they may vary greatly. It is the customers responsibility to check prices beforehand. Check the price onthe yellow-and-white label (as per the picture below), which is usually on the rear door window, beforeentering the vehicle. The highest unit price of most taxis is between SEK 350 - 440. The price on theyellow label is based on a 10 km, 15-minute journey. The price indicated on the taximeter is in Swedishkronor. For trips to and from Stockholm Arlanda Airport the major taxi companies have fixed prices ofbetween SEK 550-600. Always ask the driver beforehand. In addition to the major taxi companies thereare several independent firms; caution is advised.

Recommended taxi companies:

• Taxi Stockholm www.taxistockholm.se

• Taxi Kurir www.taxikurir.se

• Taxi 020 www.taxi020.se

Currency and credit cardsSweden is one of three EU countries (along with Denmark and the UK) that opted to keep their currencyand not use the Euro. The currency in Sweden is called the Swedish crown, or the krona (SEK). Creditand debit cards are accepted almost everywhere in Stockholm. Forex is the place to exchange money orbuy SEK. They are found throughout the city at 17 locations, including Arlanda, the train station, NKdepartment store and the Old Town. They have good exchange rates there and do money transfers aswell.

ElectricityElectrical sockets (outlets) in Sweden are one of the two European standard electrical socket types, andusually supply electricity at between 220 and 240 volts AC.
