Christina's place is the perfect home from home in Vienna. I recently stayed with my partner and 4 month old baby for 3 nights. It's spotlessly clean with everything you might need. The location is very good too. It's in a quiet street but close to shops and restaurants, and only a short walk to the underground.
Christina is also the perfect host. She went above and beyond to help us by lending us her baby sling carrier when our airline lost our pushchair. Not only that, her parents (who live in the same building) agreed to take delivery of the pushchair the following day so that we could go out because we only had the weekend in Vienna.
Don't hesitate to book! I can't recommend Christina's place enough.
