Stéphanie and her husband were very communicative, responsive, and helpful! It was very easy to coordinate the check-in/check-out. They were very accommodating with our changing situation as we had to arrive a day later instead. As for the apartment, everything is nice, clean, good shower. Internet worked well. It looks like the pictures if not better in real life! I definitely recommend this place and the location is absolutely perfect for Mitte. My favorite cafe is just down the street.
