Great room, great apartment, great location, great host. I stayed here for over a month while applying for and interviewing for jobs, and this was an ideal arrangement. I could stay at home or go to nearby cafés to get work done, I was very close to the subway for getting around town, there was plenty going on in the neighborhood if I wanted to take a break, and Katharina was always available and friendly if I needed anything.
The room is fairly plain, but it was spacious, comfortable, and well lit, which was perfect for me. The kitchen had everything I needed and I made most of my meals at home. I frequently talked to Katharina and enjoyed our conversations. She was a valuable resource for learning about the neighborhood and the city. She had family and friends over several times and I was always included if I wanted to hang out.
Katharina was traveling for most of the first couple weeks I was in town, but she was still communicative and helpful. There were some problems with internet connectivity during that time, but she helped me try to resolve them, and even got a neighbor to help call the internet service provider. (Ultimately, she got a new router, so the problems should be gone!)
This was as good of an experience as I think would be possible for what I was trying to do.
