I'm looking for a flat where 2 people can get in to live, (18è or 19è arrondissements better) my friend and I, both Erasmus.

We are spanish, we like to meet people and have a good flat environment. We are also quiet and we like to have our time to work. We plan to go out to get to know Paris. As we are going to study at Paris 8 we need a flat as close as possible to the north, but we would like still close to the city centre. We can't afford to pay more than 400 euros each one of us.
