Postgrad searching for Accommodation in Belfast

Hello, my name is Nicole and I am a postgrad student attending Queen's this year. I graduated with a Bsc from UCD and I am originally from Latvia. I'm looking for a room with other students or young professionals. My budget would be between £300-£400 and the accommodation should be relatively close to Queen's campus (within 30minute walking distance).
I would like to live with housemates who are open to being friends and socializing, but also understand that the work involved with a postgrad requires some quiet. I would prefer to live in a house that has mainly female tenants.
I'm passionate about community work and volunteering and have a keen interest in art, music, films and the environment.
