Kai and Nina recently hosted a co-worker and I for a business trip. They were very communicative and incredibly accommodating with granting us access to the apartment even with our late night arrival. The location is easily accessible and surrounded by tons of great places to eat and drink. Very thoughtful, when I accidentally left my planner behind they contacted me to let me know and made it easy for me to retrieve before I left town. Not to mention, the apartment is beautiful and very spacious with a lovely outside space. I highly recommend!!
