Stayed here with my friend for 2 nights for the wonderful Vienna Christmas markets.
Communication was top notch with quick replies.
Check-in was seamless and was tailored to our arrival time.
Flat itself was spacious, clean, comfortable.
Great location -about a 15 minute walk from the CAT Train to the airport and easy to walk to most attractions in Vienna.
We had an evening flight, and they helpfully let us keep our stuff in the flat during the day.
All in all, an excellent experience. Would reccomend this place to anyone.
