Yaz's, apartment was very clean and very close to one of the U-bahn train stations, making it very convenient to get around Berlin. We toured Berlin for 4 days and this apartment was a perfect place for us to stay. Yaz met us at the apartment when we arrived to hand off the keys and provide suggestions on restaurants, landmarks, grocery stores, etc. He was also very attentive via messaging and available to answer any questions we had once we settled in. I would recommend anyone touring around Berlin to stay here.
