The best thing about Katharina's place I would say is location location location! Beautiful located in a quiet neighborhood in Munich that is about ~5 minutes away from public transportation and 3 metro stops away from Marienplatz and 5 metro stops away from Munich Hbf.
On top of that, Katharina offered amazing welcome gifts (candy, chocolate, water) basically the essentials that a hungry traveler needs to make his day and get excited to explore the city.
The place is well furnished and well maintained and very adequate for 2 people to spend a weekend in Munich
