Looking for a decent furnished room for a student

I’m a new international master’s student at Hochschule Bremerhaven studying process engineering and energy technology. I’m looking for a long-term room rent, probably for a minimum of 1 year’s rent and with a maximum of €400 per month total. As for myself, I mainly tend to go out and explore or take some shots for content as I am a photographer and a content creator, so I might be a little bit creative on the side of social media content stuff. I never leave myself for laziness or boredom, so you either find me having fun with lads or playing video games. I intend to adjust everything to a position of being clean and tidy. I may be shy at first, but by the time you could even know my whole life story over some tea. I’m normally quite especially when I’m studying because I give 100% effort when studying.
