Professional working british guy looking for WG Zimmer in Salzgitter/Braunschweig area for 1 month - July 01st to July 28th

Hi All,
I’m Ricardo. A professional working and living in Hamburg since 2015. However my work (which is commodity trading) will take me to Salzgitter for 1 month, from July 01st until approximately July 28. Therefore I am looking for a shared apartment, already furnished in and around the Salzgitter and Braunschweig area.
I will often be weekends back to Hamburg so, not too much time at home(only after work). As it states in my profile I am British, I can also speak relatively good German too. In addition, i’m 32 years old, not a smoker and a regular gym-goer.

Thanks and I look forward to hearing from you.
