My recent stay at Charlottenburg was overall a positive experience. The apartment was spacious, clean, and well-appointed with all the amenities I needed for a comfortable stay. The host was communicative and helpful. The location was ideal - close to the train station and many landmarks.
One of the best things about this place is its convenience - it's located very close to the train station, making it easy to get around the city. Despite being close to the train station, I found the apartment to be relatively quiet and peaceful, which was great.
However, it's worth noting that you will have to share a bathroom with other guests staying in the apartment. And the apartment has a wooden platform that makes noise whenever you move. However, if It's not an issue, you are okay with being mindful of your movements and keeping things relatively quiet, then I highly recommend this place.
Overall, a convenient and comfortable stay.
