Dan's apartment is very central and only a short walk across the river tot he St Stephen's church and lots of bars and restaurants. The apartment itself is perfect for a couple of nights, it is clean and comfortable. The cooking facilities are basic so don't plan on cooking a full meal but we managed eggs for breakfast just fine! Vienna is lovely, we could have spent longer here. If you are going on a weekend do take into account that shops on Saturday close early and apart from cafes and restaurants around the touristy area a lot is closed on Sunday too. A shock for 2 people form London!!
