Heikel's apartment is wonderfully placed on Gumperdorfersraße which is both very central (and thus convenient for local amenities/attractions) yet somehow very quiet and shielded from the bustling city around it. Perfectly placed for city break with busy days planned and to allow rest at night.
The apartment was very clean and well presented, with all the necessary furnishings needed to make whatever time is spent the dwelling. My partner and I had an extremely pleasant stay and I would not hesitate to recommend Heikel to others, or to stay again myself.
Thanks for a great trip to Vienna.
