There are two big rooms in the flat (plus kitchen, bath, corridor) and a nice small balcony all for yourself.
It is bright, clean, and nicely decorated and is located very central next to many cafes, restaurants, bakerys and a supermarket.
The big fair-area "Messe/Ost Expo-Plaza" (where the IAA will be) is directly reachable with the subway 6 within 30 min.
Please feel free to ask if you have any questions.
I am looking forward to welcome you,
