First and foremost, our host receives 5 stars for hospitality, patience and caring.
The location of the apartment is excellent, about 3-4 minutes walk from a metro station and 10 minutes walk from Park & Ride (reasonably cheap parking lot).
The apartment was clean and well maintained and roomy enough to comfortably accommodate a family with 3 kids. Beds were clean and comfortable. Warm water in the bathroom were virtually unlimited. The kitchen, although quite functional, was missing a microwave but the over and electric stove compensated well for that. There was no TV in the apartment but when you're visiting a city like Vienna, who needs TV? :)
