Carsten is a great host who was pleasant, easy to reach, and more than willing to give us a great tour of the flat. The flat itself is very nice, a good size for a couple or for 3 or 4 people. Everything was clean and well functioning, and there is a very pretty balcony with good views of the city. The location is also excellent, with lots of nice bars on the surrounding streets and great transport links all over the city.
