My stay at Gerrit's was everything I could have hoped for! The apartment is a very nice altbau, comfortably furnished with a wall of books to peruse (and travel books to use during your stay) and a kitchen stocked with any utensils you will need. The neighborhood is rich in boutiques, cafes, and neighborhood bars and is well-connected with city transit. Although Gerrit was abroad during my stay, he was a lovely host from afar and I was able to get in touch with him if any problems arose (which, in nearly two months there, none did). His neighbors were also available to show me the place and help me with anything I needed as well. Highly recommend!
