I would highly recommend Katharina's place for anyone coming to Munich. It was a (shockingly) quick and convenient trip to the center of the city, and all of the places you'll likely want to see. And yet it felt tranquil and a million miles away from the hustle and bustle. The neighborhood is also full of cute little restaurants and shops, so if you just want to hang around close to the apartment you won't be disappointed.
The apartment itself is lovely, quiet, and comfortable. Although it's not the largest, it's so well designed and laid out that it feels much larger than its size. Katharina also made sure it had everything we needed for a lovely stay.
