I was very pleased to get Rainer's promise shortly before I started my travels to Vienna. His calm and spacious flat is located in a beautiful old building in Vienna's historic center. It's easy to get there - coming form the airport and taking the airport-city train + another 10-15 mins to walk. Rainer was extremely fast in responding to any of my questions and waited for my to arrive so he could hand over keys and show me the flat. Shopping, culture, leisure - anything you might be looking for in a city like Vienna is literally next door.
