Looking to sublease a furnished room - flexible with length

Hello,
I'm moving to Saarbruecken to work as a postdoctoral researcher at the university. I would like to find a furnished room to sublease short-term to begin with - anything from 6 weeks to 3 or 4 months, while I get to know the town better. I'd prefer a 2 to 4 person flatshare.
I'm a 34 year old from New Zealand, and I have spent many years in flatshares. I like to keep my place clean and tidy, and enjoy a communal meal/drink together every now and then. I like to relax at home, but also spend a lot of time 'on the go' and hope to explore the area and beyond. I am social and enjoy outdoor activities, but prefer a quiet meal and drink with friends at home or at a pub/bar rather than loud all-night parties.

I won't be arriving in Germany until near the end of June - please message/email me! Unfortunately, I only speak English! (I have just started German classes...)
