Priscila is lovely--very prompt and accommodating. She responded quickly and thoroughly to messages. Her house is way outside of Vienna, though: from the end of the U4 line, you have to either take a bus through a little town and up a hill, or walk for 35 minutes. It takes at least 45 minutes to get to the city center. The house is hard to find, and it is easy to get lost in the winding paths up in the hills. That said, it is beautiful. Far from the city, with great views, and next to some nice forest parks. Once you get used to your location - as in, figure out the nearby bus stops and roads - you'll find the house not too inconvenient to get to during the day. The bus doesn't run after midnight. A taxi to the house from the station isn't terribly expensive.
The suite she rents out consists of a small bedroom, kitchen and bathroom. Priscila has two cats and one dog. While the dog typically stays outside of the suite or with Priscila, the cats come and go into and out of the garden through the suite bedroom window, which can be startling. The cats scratched on the window throughout the night, then cried when we let them into the house. As Priscila did not leave us instructions for taking care of her pets, and we were not aware that we would be expected to care for them in advance, we were not sure what to do with the cats. The dog is enthusiastic and sweet.
The suite is furnished with everything you could need, and Priscila is very warm and welcoming about wanting to make you feel at home. A quick warning: if you are sensitive to pet dander, mold, or strong smells, this may not be the place for you. Everything is covered in pet hair (although Priscila did make a lint roller available), the suite smells strongly of cat urine, and there is black mold on the low ceiling above the shower.
In terms of amenities: there is a washing machine, a kitchen with cooking equipment, and breakfast is theoretically included with your stay. In our case, Priscila said she would pick up breakfast on her way home (she works nights), but did not do so. It wasn't an issue though; at the bottom of the hill near the town there is a basic bakery and supermarket so you can buy your own, if necessary.
