Everything worked out smoothly from the booking till the check out! Heidi's response was always immediate and very welcome. The apartament is located in a very great area with many breakfast, lunch and dinner options. Heidi's place was very clean and nicely decorated for the arriving guests. The apartement looks like on the pictures and has an even nicer bathroom. There were various city guides and brochures available to read and find out more about Vienna. Heidi's son welcomed us as the apartament and answered any questions we had about Vienna or the stay. He also immediately recommended a place nearby to grab dinner that evenening, it offered really great food.
Overall a great stay and a great host! Would definitely book it again!
