I stayed with Astrid while traveling abroad alone for the first time. Even before my trip began, she promptly and kindly answered my questions and helped prepare me for my visit to Vienna, making my arrival by public transit very smooth. Astrid is organized and gracious. The room is quiet, clean, and petite but comfortable, perfect for one person, and her flat is splendid (she has great taste in furniture and so on). I saved money using the kitchen to eat breakfast and pack lunches, and by eating at restaurants in Astrid's neighborhood, which isn't far from the center but is not rampant with tourists! I walked to all the things I came to see-- museums, parks, churches-- but the metro is also very close and easy to use. I was happy to come back to my room at Astrid's at the end of each day... her place is a great choice for single travelers who want a taste of living in Vienna, not just touring it.
