Wolfram's Airbnb is small but cozy, located in a fantastic neighborhood, and conveniently located nearby restaurants, grocery stores, and several public transportation options. We snugly fit 5 people into the Airbnb during our stay and it is definitely doable but less than 5 would be better. Additionally, Wolfram was very helpful during our stay and very welcoming to my family and me while providing maps and helpful tips for the neighborhood and Berlin, in general. Definitely a great place to stay!
