As everyone has noted, Katharina is a superb host. Provided snacks and cut flowers, great communication, carried my 20kg bag up the stairs - she went above and beyond. During my stay Katharina would give me space but was always available to answer my queries like where is the post office etc.
The location is great and in a safe neighbourhood. Plenty of cafes, restaurants and boutiques in the area.
The room itself is spacious and has everything you could ever want.
Overall I would highly recommend this Airbnb. Thanks Katharina :)
