Manuela's place is amazing!!!! We were here for Oktoberfest, and it was perfect for our stay. It is a little farther out from the center, but you are well connected with two different metro stations a short bus ride away. Manuela is a kind host, and even left out some "american style" cookies for us in the kitchenett.
Manuela also has a great supply of local guides and maps for how to navigate her neighborhood. Highly recommend!
