To share an apartment in Budapest can be very interesting for students abroad as well as students who come to Budapest for an internship. Sharing an apartment with people is a cheap alternative to an own apartment and can also be easier if someone else is the main hirer of the apartment.
Specially for young people apartment sharing is always an alternative during the studies or even while working.
Budapest has many apartments that are more or less perfect for living with 2 or 3 people in one apartment because they have a big living room and besides some smaller rooms. Of course not everybody likes to share his or her apartment and prefers an own apartment.
