This was already the second time for me that I was staying in Harto's beautiful apartment next to Alexanderplatz and it was again a wonderful experience. The cleanliness and beauty of the apartment as well as Harto's hospitality make you feel super welcome. The communication with Harto is so lovely, Harto is always available and helpful and the check-in as well as check-out process is super uncomplicated. I can highly recommend!!
