We stayed in Detlef's apartment for about 4 months and had a wonderful experience. The apartment was well located, with lots of walking options - parks, palace, leafy streets. The bus was a convenient link from the city to the airport also. The apartment is stylishly furnished and was clean. Detlef was also a great host and promptly helped us anytime we had any requests or queries. I highly recommend this place as a quiet flat but close enough to the city.
