My husband and I spent 7 days here. It was perfect.
The kitchen was well supplied (knives were sharp!). Plenty of utensils for basic cooking.
The space was clean and inviting. The bedding was comfortable. We enjoyed just hanging out at the apartment.
When we did go out, the location is ideal. Just minutes from the U Bahn, you can get just about anywhere in Berlin easily. Also, within walking distance is great restaurants, markets and a cafe. Perfect.
The owners were very responsive to all our questions and are close by if needed. We will be back.
