2 students from Greece looking for accommondation in Porto

Me and my friend would like accommondation near the center of Porto and near the U.Porto (specifically the FIne Arts building). We would prefer not to have over 2 roommates and the rent not to be over the 250€ including the bills. We study Graphic Design and we are Greeks.The best would be to have as less roommates as possible and the apartment to be located between the center and the univeristy (U.Porto) and also the price not ot exceed the 250 euros including bills(water, electricity, internet)
