Here is a google map to show where the Zuidas Blocks is going to be placed.
There are three spots in the map.
When the weather is just cloudy and dry it’s going to be location 1: outside Zuidplein (north side of station, in the corner of station and restaurant Wagamama)
When it is raining from the morning it’s going to be location 2: WTC building (ground floor, go left from the reception desk near the escalator, space before big hall )
But it is not sure until the last moment if we can use the location 2. So I have reserved a space in the office of Amsterdam Bright City: location 3(Claude Debussylaan 2-8)
Check the locations in the map. Each location is within 3 minutes work to each other.
