April 4th

LDBC plenary meeting for project partners.


The meeting will be held at the Dutch national research institute for computer science and mathematics (CWI - Centrum voor Wiskunde en Informatica). It is located at Amsterdam Science Park:

Hotel accommodation

We recommend accomodation at five hotels, at different budget price-points (from cheaper to more expensive – prices based on recent quote, breakfast inclusive):


Arriving & departing:

Amsterdam has a well-functioning and nearby airport called Schiphol (AMS that serves all main European carriers and also very many low-fare carriers.

Trains (~5 per hour) are the most convenient means of transport between Schiphol airport and Amsterdam city center, the Centraal Station (17 minutes, a train every 15 minutes) – which station you are also likely arriving at in case of an international train trip.

From the Centraal Station in Amsterdam, there is a direct train (every half an hour, runs 11 minutes) to the Science Park station, which is walking distance of CWI. If you go from the Centraal Station to one of the hotels, you should take tram 9 – it starts at Centraal Station (exception: for Hotel Casa 400, you should take the metro to Amstel station - any of the metros will do).

Taxi is an alternative, though expensive. The price from Schiphol will be around EUR45 to the CWI or another point in the city center (depending on traffic, the ride is 20-30 minutes).

Public transportation (tram, bus, metro) tickets for a single ride and 1-day (24 hour) passes can be purchased from the driver/conductor on trams and busss (cash only) and from vending machines in the metro stations.

Details about the metro, trams and buses, including the electronic ticket system ("OV-chipcard") can be found here:

Only the "disposable" cards are interesting for you as visitor.

Multi-day (up to 7-days/168 hours) passes can only be purchased from the vending machines or from the ticket office opposite of Centraal Station. For details see or

Getting Around: the fastest way to move in the city of Amsterdam generally is by bicycle. Consider renting such a device at your hotel. For getting from your hotel to the CWI, you can either take a taxi (expensive), have a long walk (35min), use public transportation (for NH Tropen/The Manor take bus 40 from Muiderpoort Station, for Hotel Casa 400 same bus 40 but from Amstel station, and for the Rembrandt Hotel it is tram 9 until Middenweg/Kruislaan and then bus 40), or indeed bike for 12 minutes.


In case you plan to arrive by car, please be aware that parking space in Amsterdam is scarce and hence very expensive. But, you can park your car on the "WCW" terrain where CWI is located. To enter the terrain by car, you have to get a ticket from the machine at the gate. To leave the terrain, again, you can get an exit ticket from the CWI reception.

Arriving at CWI: Once you arrive at CWI, you need to meet the reception, and tell them that you are attending the LDBC TUC meeting. Then, you'll receive a visitor's pass that allows you to enter our building.

Social Dinner

The social dinner will take place at 7 pm on April 3 in Restaurant Boom (, Linneausstraat 63, Amsterdam.

Travel costs

There is some small budget available that can be used to assist some attendees that are otherwise unable to fund their trip. Please contact us using the following email address if you would like more information: ldbcgrants AT ac DOT upc DOT edu
