My family includes amongst its members people of color. Based on our experience, we cannot recommend the subject apartment. I am saddened to say the interpersonal environment proved toxic.
We have been visiting Garmisch for 40 years on 10 plus separate vacations. We love the area. The citizens are overwhelmingly very friendly and accommodating. We found the parishioners of St. Martin's Catholic Church to be particularly lovely people.
The apartment in question is 1 of 5 in the building located on the top floor. The facilities and location are excellent. The only problem with the apartment itself is that it is not air conditioned and we needed to purchase two room fans ourselves to keep the living space reasonably comfortable with summer temperatures. But, overall, it is both nicely maintained and spacious.
Most importantly, however, apart from the Building Manager's spouse, the encountered tenants and Building Manager can, most generously, be depicted as unfriendly although a more exacting description would be hostile, ranging from passive-aggressive to outwardly belligerent. We can’t envision using this accommodation again.
