What a great place. It is right by the metro, which then takes about 4 minutes to get you central. I imagine it is very walkable too, but this was winter and it was something like -1 degrees, so I didn't try!
I was only in Munich for the one day, but this apartment made it easy for me to get to the Brandhorst (which I really wanted to see), and the Christmas markets. I'm already thinking that I'd like to come back to to city with my girlfriend, and I'd look to stay here for sure.
All communication was quick, and painless. I'd recommend heartily.
