Henrik's place is a great option for anyone visiting Berlin. Its located close to the city center but not too close that it is loud. As an American I appreciated that its just down the street from a cafe that is open early with coffee. Its also just down the street from local restaurants, a place where you can buy beer, bars, and a grocery store.
Henrik was great about getting in touch with us and making sure we had everything we needed to check in. The place was clean and well equipped with everything someone staying a few days needed. We happened to be in Berlin in the middle of a heat wave but even without air conditioning Henrik's apartment was comfortable. We would definitely stay here again if we came back to Berlin.
