We brought our 16-year old niece to Berlin to show her the city and look at colleges and this apartment met our needs for space very well with the 2 bedrooms. It was also decorated nicely with furniture in an antique style that was prettier than it was comfortable. There was a heat wave during our stay but the apartment ventilated well with the windows and use of fans. I recommend earplugs to help with road and business noise when the windows are open. I do not recommend this apartment for anyone with severe knee or mobility problems as the stairs up to the bathroom are extremely steep and awkward, and also the step into the bath tub, but for anyone else, it's fine. It was very convenient to have our own laundry room, especially since the extreme heat during our stay meant we had to wash clothes more often. The wi-fi didn't really work on our American phones, even when we used German sim cards. Overall, I enjoyed the apartment. I liked the high ceilings and old world charm. It was just a short walk to the Charlottenburg S-Bahn station so getting around was very easy. If I need a two bedroom apartment in the future, I would consider staying there again.
