This was hands down one of the best places I rented. It's in a well built block of flats, everything is super clean and tidy, the check-in/check-out are both flawless and the only time I had to call the Numa support, they got me through the problem with no waiting time (and the problem was that I forgot my code).
The flat is clean and very well equipped and the host really goes the extra mile to get you feeling comfy. There were complementary snacks and water, the place is equipped with friendly notes to help you get the most of the trip.
While it's not walking distance to the Munich old town, there is a free-parking zone and you can park directly in front of the place and either drive or take the bus to the centre.
