22 years old mexican guy looking for flatmates (January-May 2019)

I'm a 22 years old mexican guy going for an exchange semester in January 2019. I'll be studying at Siences Po. Im looking for flatmates. My budget is between €650 and €800. I would like to rent from the middle of Jannuary to the end of May. I'm searching for at least 1 roommate, but also open to more rommies. I would like something around the 6th or 7th district, but I'm open to going further away from those districts if the appartments that area are too expensive.
