How to get there
The Oosterkerk (Google Maps) is most easily reached by bus 42 from Centraal Station, which stops right in front of it. You can also take tram 1 and walk for two minutes.
Please check these instructions again just before the conference. Amsterdam public transport has an unfortunate tendency to suddenly change due to the innumerable building and repair projects in the city.
During performance.now() the venue will still have scaffolding on the outside. The interior is conference-ready.
