Lodging
An inexpensive choice: Stayokay Hostel
For solo travelers we recommend the Stayokay Hostel, which typically has beds for about €55 per night, including a simple breakfast. (Towel rental is €3.50.) It’s a typical hostel in the world-famous “Cube houses”, two metro stops away from Nieuwe Instituut.
Other lodging
Of course you’re free to make your own arrangements. Rotterdam is a popular destination that becomes expensive as the dates approach, so book early! (Booking.com link, Google Maps link)
