Looking for a nice flat in Cihangir/Besiktas/Sisli

My boyfriend and me are studiying here in Istanbul with erasmus till End July 2016. I am studying Master of Architecture and my boyfriend studies Master of Landscape Architecture. In Istanbul we study half a year at the ITU. We would describe ourselves as easy, calm, tidy, open-minded, autonomous and reliable. In the six months we would like to get to know Istanbuls beautiful edges, but we also want to enjoy our time in a cozy, tidy and nice flat. Our interests are music, temporary dance (Lisa), of course architecture, culture, and art. We are looking forward to hearing from you
