Most schools have some student housing available and will help their international students find a place to live.
Most educational institutions in Delft help their international students apply for student housing. Duwo, a student housing corporation, is the largest supplier of student housing in Delft. Duwo works together with most schools in Delft (including TU Delft and Unesco-IHE) to provide safe, affordable housing to the thousands of Delft students. Be sure to apply early.
For other housing options, take a look at a home to rent.
