Postgraduate student at University of Bremen, looking for accommodation

I am looking for a studio apartment or a private room in a shared apartment in Bremen. My budget is 350EUR including utilities. I will be living there for 1-2 years. I would like to have atleast a shared/private kitchen and a shared/private bathroom. I would like to have 1-2 other flat mates. I would prefer a place where guests are allowed and with a deposit of 1 months’ rent. I would like the private room/apartment to be furnished with a cot, mattress, cupboard, study table, stove, microwave and oven in the kitchen.
