Very nice apartment. Communication is very easy and quick responses. The airbnb is located close (5 minute walk) to two underground and one s-bahn station. It was clean and big enough for 2-3 people. The kitchen is sufficient to make a small breakfast or dinner, would recommend to bring essentials like salt, pepper, oil etc., but utensils are present. You can leave your baggage before and after check-in/out with them, which was very nice since our train arrived hours before and after check-in/out. Would recommend for a nice and quiet stay in Berlin!
