After two successful transactions with Ms. Tietze, it was clear to also carry out the third sale with Ms. Tietze. From the preparation of the exposé to the notary appointment, everything went smoothly. Ms. Tietze was competent at all times, answered all questions in detail, was available at all times, sometimes even on Sundays, and Ms. Tietze was always polite, nice, helpful and friendly. I can only recommend Ms. Tietze and SIS. B.B.
