Great apartment! We were 3 single people with plenty of space. There's a lot of great restaurants right next to the apartment, and about a 20-30 min walk to the Brandenburg Gate. If you have a car, do not plan on being able to park near the apartment. Berno is one of the most engaging hosts I've had on Airbnb. He is very responsive and helpful. He inquired periodically during our stay and offered suggestions on different things to do depending on where we were. Much appreciated!
The only thing to be aware of is the parking. I had to drop everyone off and the bags and then drive around for a hour looking for a spot.
