Looking for a long term accommodation in Künzelsau preferably in close vicinity of Hochschule Heilbronn Künzelsau Campus

I am Student in Munich and would be staying for approximately 1-2 years for my project in Künzelsau. I am looking for a room in a shared flat or a studio apartment . The maximum rent I can afford is around 250 euros. I would be moving in from September 2021. It would be great if I can get some leads so that I can have sufficient time to plan out things. I am open to roommates of all genders but would prefer roommates that do not smoke. I am a vegetarian, Indian by origin and I cook my food . I prefer peaceful atmosphere but would also like the room to be in the city center with good transport connectivity and close proximity to grocery and stationery shops. Kindly let me know if there are any genuine options that suit my requirements. I look forward to hearing positive soon
