This is a brilliant place to stay in Berlin.
The apartment is very well located close to checkpoint Charlie and you can get all over town by public transport or simply walking.
The apartment is extremely secure and the brand-new Wi-Fi works like a charm
We were able to enjoy Berlin as we expected
Every morning we would walk to Brandenburg gate, find a coffee shop, wander back and get ready for the day ahead.
We highly recommend this Airbnb and thank the owners for their attention to detail.
Although we stayed in summer, the double glazing and hydronic heating will make it as warm as toast, I have no doubt.
