Wohnung für meine Praktikum im Aachen

Hello, I am an American biomedical engineer (25M) from Texas A&M University looking for a pet friendly flat in Aachen starting in August. I am conversational in German, and happy to speak it, but am writing this in English to avoid misunderstandings due to my limited language skill and lack of recent practice.

I plan to bring my 3 year old dog, Noodle, shown in the pictures attached. She is a very sweet dog once she warms up to people, and well behaved.

Information about me:
I recently graduated from Texas A&M University with a degree in biomedical engineering, and before that I spent 3 years in the US Army. Despite both those things I am politically fairly liberal, something I'm clarifying because people tend to assume I'm conservative based on my career path and Texas residence.
For my hobbies I like to go out with friends (during non-corona times), read, play video games, cook/bake, watch shows, and am an amateur "maker." Most recently I made a 1:24 scale model of my apartment out of cardboard. I also really enjoy biking, it has been my primary mode of transportation for the last 4 years.

I'm pretty social, up to a point, and quiet as a tenant. I try to be considerate of those around me. Also when I cook I tend to cook in large batches and am usually happy to share what I've made with the household. It's more fun that way.

Feel free to contact me with questions!
