We arrived early but Carmen met us within minutes of our arrival. The place was charming, clean, quiet, and nicely decorated (even with the furniture in larger room oddly arranged). The location was close to bus and Ubahn, the kitchen well-equipped, the shower fantastic, and the heating units well located.
Only note would be about the linens, which were rationed, basically. Only one bed was made up, and we had only two small hand towels. Consider bringing your own wash cloths and a second kitchen towel.
