Viktoria was not available but we met Miriam, her cousin. She was very helpful, courteous and punctual. Our checkin and checkout times were very early and she was always there on time. Was constantly in contact on WhatsApp and giving us pointers about things to do and other logistics.
The apartment is located close to the Naschtmarkt and to the shopping street. Its also a 20 minute walk to Museum Quarter.
The apartment was clean and more than spacious for 2 person.
If you are 2-4 people, this is a good deal given location and convenience.
