From the reviews, I expected Sofia’s place to be small, but it was plenty big for the five of us. Especially since we only needed the place to sleep, shower, and cook small meals.
The rooms did get a bit stuffy, and since it was snowing/raining our entire trip, we were not able to open any windows. On that note, if you do cook any large meals, the living area (and bed for the fifth person) will smell like food for a while since there is no vent/fan above the stove.
Sofia and her husband were great hosts. They provided maps, print outs, etc. with all the information any travelers would need. The location is also close to many great Munich attractions. Their English is very good, so communication was perfect.
