We stayed at Cecilia's place for almost 3 months as we settled into Berlin. The space is great for a couple, has a great little kitchen, a powerful shower, and the bed was very comfortable.
I would happily recommend Cecilia and her place to anyone looking to stay in Berlin. The location is wonderful and super easy to get to town, along with markets and the wider S Bahn ring. There are plenty of supermarkets nearby, and some cute cafes.
Thanks again for the hospitality Cecilia.
