I rented Rainer's apartment with a colleague for a business trip to Vienna. I had never used AirBnB before so was a little cautious. My colleague who arrived a day earlier than myself had his flight delayed by several hours and arrived late in the evening.
Rainer and his wife were excellent, my colleague collected keys from their own home much later than previewed and without a fuss.
The apartment is spacious, well situated and a short walk to Praterstern and Nestroyplatz underground stops. It is also a stones throw from the river front. Vienna was icy cold but the apartment stayed warm and the shower is hot. I can recommend without hesitation staying at Rainer's apartment. Nice Host and a nice flat.
