Staying with Kurt is great. The flat is very friendly, well organized and clean. Location and connections to downtown are as stated, easy and convenient. The guest room and extra bathroom are comfortable and cosy. He also allowed us to use his living room sofa as a bed which was surprisingly comfortable as well.
Kurt is a very nice person, welcoming and helpful - to that extend that he even drove us back to the airport on an early Sunday morning... Definitely recommended!
