Staying with Anne and Julian was a very pleasont suprise and a real "Airbnb experience". They left the me the full appartment for the weekend, so I could use a >80 m^2 "Gründerzeit" appartment in the hip 6th district close to U4. The place is beautiful with a small balcony to an inner courtyard, modern kitchen, and stylish living room. Anne and Julian (I met them at check in/out) are a very amiable couple, and interesting to chat about (old) films and preserving/archiving them.
