The apartment was fantastic. It was literally a block away from a large park and right on tram and bus lines. The apartment offers a lot of privacy even though it's on a main road. While it can get a bit noisy in the mornings, overall it is an oasis.
I unfortunately didn't have a chance to meet Mirjam but I did meet her husband, Didi, and he was extremely helpful and offered up some great suggestions for bakeries, museums and cultural events.
