Stayed in two different units on this trip (this one-BR and a very large design studio called the beletage, which was more expensive) and I have to say that this 1Br unit was the better unit/value.
Location: you’re not in the heart of Neukölln or Kreuzberg next to all the hip bars but you’re on a really beautiful street in Schöneberg (arguably most central neighborhood) within minutes of both S and U-Bahn stations. Really nice spot. And we didn’t find being so close to the S-Bahn to be an issue noise wise.
Unit: The unit had lovely massive windows, high ceiling with cool scalloped brick. Bed was very comfy. Furnishings in the living area were basic (smallest couch I’ve ever seen) and there was a small TV which was fine because it didn’t encourage us to use it.
The bathroom was the only thing that left something to be desired. No tub and the room as a whole was not especially inviting but it fulfilled its core functions.
But overall a super nice vacation apartment.
Noise: as I said didn’t notice the s-bahn but the hallway door opening and people walking in the hallway can be heard. Luckily it was not particularly high traffic while I was there so that these sounds were not too disturbing.
