My friend and I were in Berlin for a weekend to see the Christmas markets and enjoy the city. Ursula had already been very helpful in details of how to get to the flat from the airport and was there to meet us, even when we had arrived late due to our flight being delayed.
The flat was more lovely and individual than the pictures even show - light, airy and unique, not to mention spotlessly clean. Everything you could want from towels and toiletries to English guidebooks and fresh coffee were waiting for us.
The location is perfect for exploring the local neighbourhood of Kreuzberg. It is also very close to the U-Bahn to get around the city.
Berlin is a brilliant city and people like Ursula and her lovely flat make it more so - could not recommend enough!
