Hotels

Within walking distance to the office (5-10 minutes) are, e.g.:

• Eurostars Grand Central Arnulfstr. 35, 80636 München

• Novotel München City Arnulfpark Arnulfstr. 57, 80636 München

The area around the new office isn't particularly thrilling, though, so you might want to choose a hotel closer to the center. Anywhere around the center is nice, only the neighbourhood next to the main train station is slightly more shabby.

The city is very well connected by public transportation, and the office is easily reachable by either Tram (line 16 or 17, stop Deroystraße or Marsstraße) or S-Bahn (light rail, any line, stop Donnersberger Brücke) -- it's a 6 minute S-Bahn ride from Marienplatz. Be aware that the office has no parking space.

Unofficial community reception

The Munich JavaScript community would like to meet us! Hosted by Axel Rauschmayer/MunichJS, sponsored by adesso AG. event page. On Sunday at 6:00 PM, food and drinks provided, optional Q&A panel. No need to register for this event if you are a TC39 member.
