Except those offers in which the employer provides lodging, IAESTE trainees in Spain are usually to be lodged in shared flats with other students. As a rule of thumb, most trainees working within 30km of any regional capital city will live in it, where the IAESTE Local Committees are located.
We look for (typically single) rooms to rent in student flats who go home for the summer. We require owners to allow full use of bathroom and kitchen, but that’s about all. We try our hardest to search for rents under 250 euros a month, but is is not always possible (in the summer there’s the added pressure of massive tourism).
