Gudrun's apartment was PERFECT for my 2 night stay. It's extremely well located being in the center, walkable to most anywhere you'd like to go. Public transport very close too. The interior was very nicely decorated and spotless, nice bed with added padding for even more comfort, and the space was stocked with everything nec and more. Armin met me there and was extremely professional and gracious letting me drop my bags a little early. Communication fast. Hard to beat, it was the most comfortable, easy, well located stay during my 4+ weeks in Europe! Top notch, will stay again when returning. Highly recommend.
