This was our first experience with AirBnB, and it was great! Robert was extremely helpful right from the beginning, when we had booked the apartment, till we reached there and throughout our entire stay. The apartment is spotlessly clean, exactly as it shows in the pictures. The gadgets work perfectly. Location is also good, buses and trams are available right on the doorstep, groceries and restaurants are nearby. Robert is a wonderful host, very fast to respond, and tried his best to make our stay comfortable. The only flipside, I would like to mention, is the early checkout time at 10am. We had a flight at 3:30 and had to wait in the airport for a long time, so an hour of flexibility in check out would have been great. We indeed enjoyed our stay, and would strongly recommend our friends who would visit Vienna to stay here.
