The place at Alex's house is beautiful and really comfortable. The room is spacious, warm, and it has plenty of natural light. We were provided with maps and brochures with very useful info about Berlin, and our hosts were always open to answer our questions and we had super interesting conversations whit them. The location of the place is really good, just 5 minutes walking from U-Bahn - S-Bahn station. The neighborhood is safe and full of stores and small restaurants to eat in. It was just perfect.
