due to a cancelled project, I have a furnished apartment in the middle of the city for rent. It is located right at the Schlossplatz (1 minute walking distance) on the fifth and top floor of an otherwise only for business purposes used house.
So you can't live more central than that, still you don't hear street noise.
The house has an elevator and internet as well as cleaning service is included. The apartment is fully furnished including a kitchen and has a washing machine as well.
It is available on short notice and has relatively flexible moving out options. So it is mainly cut for project workers looking for a temporary apartment in Stuttgart.
As an all-inclusive price (no further payments for energy, gas etc.) I'm thinking about 1.200 EUR per month.
Please contact me if you're interested or you know anyone who's looking for such an apartment.
