We had a really great time at Nadia's appartment! Nadia's mother, Dagmar, received us and made us feel at home immediately. She gave plenty of advise about what to do in Vienna, where to do shopping, etc. The appartment is very well equiped: many brochures and travel guides about Vienna, towels and sheets, and cooking equipment. The fridge was full (even too full for the two of us) with food, so we indulged in some great breakfasts. Furthermore the appartment is really cosy, with many paintings hanging on the walls and shelves full of books.
The location was also perfect: right across the Prater Park but no street noise.
In short, Nadia and Dagmar, and their appartment, exceded our expectations by far, and made us wanting to return immediately!
