A number of team members are staying at the NH Hotel Museum Quarter. There are also some other NH Hotels close to the event space (Weteringschans 28). According to our hosts the best option for more affordable accommodation is AirBnB. The next best option is to contact https://www.frederic.nl/en/
to see what rooms they have available at that time. They're a bike rental shop in the Jordaan neighborhood (very close to Central Station) and they also rent out affordable rooms around there. And the third best option is the Eden Rembrandt Hotel located at Rembrandtplein. Their rates are not cheap but they're not outrageous either.
