We had a great stay at Mike and Franzi's place! It is their own apartment, which they rent out on airbnb when away on vacation. Very well maintained, clean and conveniently located, just 10 mins subway ride from the center. Mike and Franzi were kind enough to let us check in a bit early, and leave our bags in the apartment after checkout. They were also very responsive to messages and recommended things to do around the city. Amazing hospitality, cozy apartment, would definitely recommend this stay!
