Room for a Newcomer Architect in Dortmund

Hi! My name is Ludmila. I am looking for a room with possible anmeldung in Dortmund from January onwards. My budget is 500 max.

Who am I and what I am looking for?
I am 33 years old and come from Argentina. I work as an Architect and I start working in Dortmund, then I am looking for a room in a friendly WG to move in. As I am going to be new in the city and the job, it would be ideal if I could find a short-term room, for the first months.
I speak Spanish, English, and German. I really want to improve my German, so I would be more than happy to live in a Deustchesparige WG.

How am I as a roommate?
I am a quiet, easygoing, and flexible person, who enjoys cooking and loves cats. I would really like to share spontaneous conversations, activities, and/or a drink with my roommates, but always keep my own space to chill out and take care of my personal activities. About cleaning, I am very respectful and will be extra careful to keep everything tidy in common spaces.

What do I like to do?

Photography is one of my favorite activities, so long walks in the city with my camera will be part of my routine. I also like attending different cultural events, such as festivals, exhibitions, or movies.
