Searching for small one room appartment

Hi, I’m Faith. I am a 35 year old English woman looking for a long term rental within Berlin. I would prefer a small private studio with a kitchenette and most bills included for 600 euro. Unfurnished would be fine as I have some stuff from my current appartment. I would prefer a location within the Ring however if good transportation links are nearby then I would reaccess.

I work full time. And I’m a quiet and respectful individual. I’m just looking for my own private space to have some peace of mind. I co-own a dog from my previous relationship and he would occasionally stay with me but only on some weekends. He doesnt bark and is house trained.
