Marine's flat was really lovely, stylish, and quiet. It had everything we needed for cooking (including an immersion blender!) and cleaning, and the building itself is wonderful. We stayed for a full two months, so the location worked well for us, but it is in a quiet area, and is a 10 minute walk to the U-bahn and S-bahn, which might not be ideal for those who are only passing through Berlin. Marine was easy to communicate with and coordinate with. All in all, we'd highly recommend it.
