The University of Amsterdam itself also offers help to link students to a house. Throughout the city there are buildings with only UvA student rooms. So you will also be surrounded by fellow students. There are four different types of rooms with their own price range. This site explains everything very clearly, so be sure to take a look!
The UvA has reserved a certain amount of student rooms with different housing providers and can accommodate roughly half of the newly incoming (1st-year Bachelors or Masters) international students. If they cannot offer you a room, you will have to find accommodation on your own (check out the section RentSlam and other housing websites). We advise you to apply for student housing as soon as you can, as Amsterdam is experiencing a significant housing crisis and there is a considerable shortage.
