Wonderful host! We stayed as a family of 4. Johann helped us arrange for a babysitter ahead of our arrival, so we could experience the Berlin club scene one night. She was wonderful with the kids. He also let us drop our luggage off ahead of check in time, which was immensely helpful. We loved being across the street from a park/playground and also great restaurants, bars, and a grocery store just a short walk away. the unit had everything we needed, including a washer AND dryer (first one we've seen in all of Europe!) and detergent. the only thing we didn't anticipate was that there is not a great dining area. there are 4 bar stools in the kitchen but you're basically staring at a wall while you eat (plus our kids age 6/7 were spinning the whole time which drove us crazy as it's a tight space). we ended up sitting on the floor around the coffee table instead, which was better for us. All in all, we had a great time. thank you, Johann.
