The Instituut-Lorentz is at the second floor of the Oort building (slanted by 7^o, next to a tall building covered with black panels).

How to get there: Take a train to Leiden Central Station (20 minutes from Amsterdam Schiphol airport). From the train station, you can either walk along the Rijnsburgerweg and the Wassenaarseweg (20 minutes), use a rental bike (OV-fiets), take a taxi, or take bus number 37 to Katwijk (get out at the stop "Corpus", just before a sharp curve in the Wassenaarseweg), or number 38 to Katwijk (get out at "Universiteitsterrein"), or 43 to Den Haag (get out at "Bio Science Park Oost"). Each bus ride takes less than 10 minutes, leaving the station twice an hour.
Here is a detailed map of our neighborhood, and here is a map of downtown Leiden (connected to the detailed map in the upper left hand corner). Some nearby hotels are on this map.

By car: Public parking at the Ehrenfestweg: a large garage with wooden frame in front of a round lecture hall with red roof. Cost 2 Euro/hour, which you may avoid by calling your host in advance to arrange free entry based on your license plate.
