I booked Yaz's apartment for my mother and brother for their two-week stay in Berlin. The location was a perfect base for them to discover Mitte, Kreuzberg and Neukölln. The apartment itself is basic but they found it comfortable. My mother in particular appreciated that it's slightly below ground level, as she finds stairs difficult. It's arranged so one bedroom must be passed through to reach the other bedroom, kitchen, etc, from the front door (this isn't clear from the photos). This wasn't a problem for them but some guests might prefer more privacy. They found the kitchen good but a bit limited, as they wanted to cook most meals at home. Yaz was a great, friendly host and always responded quickly to our messages. One light bulb went out and he came to fix it the next day. Overall they were very happy!
