looking a quiet flat with bath

Hello! I am a lady teacher from China. 40s; and currently learning German in Berlin. I am looking for a small quiet flat in Wedding。I will rent it for two months( Jan.10th.-March 12th). I need a one-bedroom flat with a bath. I am quiet, non-smoking and easy-going. I won't cook Chinese food with much oil and smoke. I hope the landlord is friendly and patient. I can afford the rent between 300Euro-400Euro per month. Thanks for reading!
