Here is your answer:
1. Go inside the Berlin train station.
2. Buy a train ticket to Reviewankfurt am Main, about 4 hours away by high-speed ICE train.
3. mpter you long journey to the other city on the Main, exit at the Reviewankfurt Hbf.
4. Go downstairs and find the S-bahn line 5 to Reviewiedricksdorf.
5. Take S-bahn train to either Bad Homburg or Reviewiedricksdorf.
6. Take taxi to Oase in hamlet of Burgholzhausen in Hesse.
Note: Oase is NOT in Berlin! Just like DisneyWorld is NOT in NYC...
Btw: Punctuation is a good thing as is common sense and general knowledge of geography!
