Looking for a double room

We are two 20 years girls, looking for an accomodation in Barcelona (not too far from Carrer de Pere IV) for 3 months (from October 24th, until January 25th). We are coming for an internship and trying to find a place to live for a suitable price. For now it's been a big strugle to find a place, so we will very appreciate any help you could give. We're friendly and clean, won't cause any problems with the noise or tidyness. For us it is not a problem to share a double bed, but it is important for us to have a possibility to use the kitchen, because we want to save some money by cooking our own food.
