We chose this apartment because it was positioned such that a 7-year-old could walk to the Hausberg gondola, to the train platform, and into town. (We lack a car so walking distance is critical). I liked the layout - entryway divides bedroom and living room -- since it allowed us to put our daughter to bed early in the bedroom while my spouse and I stayed up for a while in the living room. Then we moved her to the couch.
The stay would have been even better with a few tweaks to the kitchen and sofa bed. The kitchen needs scissors and a non-melanine cutting board. (I travel with my own board and knife now, but I noticed this.) Another shelf above the sink - a bit sturdier - would be nice, as would a set of mixing bowls for dinner prep.
The sofa bed would benefit from a mattress pad. We turned a blanket with some breathable fibers into a makeshift mattress pad. Otherwise, a single cotton sheet against a pleather sofa will make for an unpleasant night.
Finally, if you come by train, be aware that **some** drivers on St. Martin Strasse resent pedestrians crossing it to get into town. The nearest route has a pedestrian safety island but no zebra-striped crosswalk; a few drivers yelled at us for crossing to the island because it forced them to slow down.
