Rainer was a fantastically helpful host, allowing me to arrive early and leave my bags until my flight on my last day. He sent me helpful details on how to get to the flat and was very responsive. The flat is large, light and airy with huge windows on to a very quiet street. It's 5-10 minutes' walk from Wein Mitte (16 / 35 mins train from airport) and also very good for walking, tube and trams. And the Hilton if you are at a conference there - couldn't be easier! The flat was spotlessly clean and everything had been thought of including tea bags, olive oil, shampoo etc. Comfortable bed, wifi, hair drier, towels etc etc. I felt very well looked after. Thanks Rainer!
