Klaus is a super nice host. I arrived late at night and he came to pick me up at the train station. His girlfriend and other hosts are also very welcoming. The room is very big and warm, bed comfortable. The apartment is located at a very handy place close to city center and westbahnnof train station. Shops supermarkets and restaurants can be found easily. Plus, Klaus shared with me a lot about the history of vienna and austria. He also recommended me nice places to eat and to have a overlook of vienna. This is my best airbnb experience so far.
