Looking for a place to stay in eastern Istanbul

Hi there! I`m an English teacher in Istanbul and I live in Caddebostan near Kadikoy on the Asian side (near the centre and the transportation is easy). My house is nice and also the neighbourhood, the coast is quite close to the house so it is nice to walk, cycle there. I`m looking for a roommate. (Rent is 400Lira + expences) I have a bed etc in the room if you need or you can bring your own stuff for your room if you want. I`m quite neat and organized. I love sharing and am considered as a friendly, lively person. I love cycling (I go international biketours), mountaineering, music, cinema… If you are interested  please write to me.. Thanks..
