2 room bright apartment available

My husband and I live a beautiful 2 room apartment in Sachsenhausen. The building is modern and well maintained, have elevators and hausmeister for any support. It's in a very green locality, with a forest view. Bus stop is 5 min walk and Süd station is 15min walk. Grocery store is just downstairs. I am looking for a bigger apartment 2.5 to 3 room (located close to either Südbahnhof or Hauptbahnhof)
