You can stay at a hostel for a fixed price. Ofcourse we do know this is temporary, but in the meantime, you will have a bed and breakfast to start with. Erasmus Student Network (ESN) made deals with several hostels in The Hague. If you are interested, send an email to: firstname.lastname@example.org and you will get all the information you need. Understandable, you will have to sign up to ESN to get the proper information.
We found a few expats in Voorburg, Voorschoten and Den Haag willing to let a room (temporarily!) to international students. How about that? They know all about ‘starting a new life in The Hague’ and they have a spare room. Are you interested? Send an email to email@example.com. The student realtor is connected to ESN and will connect you to the concerning expats. Connecting you with the expat is at no cost. If you want more support, you will have to pay for it.
