We have had a really nice stay at the beautiful apartment of Patrick & Kate. The apartment was nicely decorated and had everything you needed, including a large bathtub. Thereby it was very clean. It was also useful that we had our own entrance, which gave a lot of privacy. The communication with Patrick & Kate was very easy. They responded very fast and accurate.
The location of the apartment was good, in a +-5 minute walk you're at the trainstation where the train takes you in 10 minutes to hauptbahnhof.
