The apartment is great with good amenities and great location! Everything was as described if not better! We traveled with our 10 month baby, and the host provided and set up a baby bed for us.
The host was very quick with responses, and check is was well explained and easy.
Yes it is on the lower level so have to go down (sort of like "celler") stairs, but once inside, it opens up to the outside with nice floor to ceiling windows, making it bright and open, then they also have black-out shutters too (which is invaluable for us with a baby!)
Perfect location, quick, easy walk into the centre, parking garage right across the street, groceries, etc. around the corner, everything you need.
I would highly recommend this apartment and we would certainly return on our next trip to Munich.
