Christian and Anja's apartment is very nice and pretty well located, very close to the center (10 minutes walk to the Museum quarter) without being submerged in the crowd, with shops and restaurants all around.
The pictures describe perfectly the flat as it is: lovely and well-equipped even with little extras like sparkling wine and wafers.
Christian has also been a very nice host, even paying our first hour of parking as we did not know how it worked there.
Well, definitely a lovely place!
