Anna’s place is awesome... location, design, communication all worked perfectly for my wife, 2 daughters and myself. I absolutely recommend this place if traveling to Munich for business or pleasure.
It’s located on a main avenue and next to the metro, to supermarkets and pharmacies and to nice restaurants.
Only thing to be aware is that, as in most buildings in Munich, there is no elevator so try to travel light or be ready to carry your stuff up 4 floors.
