We stayed one night at the apartment, Erich greeted us in person and was very nice. The apartment is spacious and beautifully furnished, the location is excellent for touring the city. Kitchen was slightly dirty and the A/C in the top floor didn't manage to cool all 3 floors of the apartment perfectly, but it still was okay. (I have to add it was during a heat wave (32°C) and there were 8 people in the apartment). Would definitely recommend Erich and the apartment.
