The house was very clean, well-furnished, and very lovely from the outside. The garden, the pine trees, and the pool just in front of it created a very calm and soothing atmosphere. I could enjoy breakfasts and lunches in the open air on the terrace. The heating and air conditioning systems allowed to quickly manage the temperature inside. It was overall very quiet, which made this location so different from my previous accommodation experiences in Vienna.
The Internet connection was fast and reliable, although it worked through a cellular network rather than an optic cable or other wired medium. This was a big and pleasant surprise.
I shall also particularly appreciate Daniela's hospitality, help, and communication. The entire experience felt like staying at your friend's place. Daniela also generously offered to use a free private parking spot in front of her house -- so if you arrive by car, contact her about it beforehand. Also keep in mind that the neighborhood is located on top of a hill overlooking a large vineyard. The view is beautiful, and the hill is quite steep, so if you have heavy luggage like I did, I suggest you come and leave by car. When it comes to transportation options while in this location, my personal preference would be also renting a car. There's a bus (10 mins to the Hernals S-Bahn Station, every 20-30 minutes on schedule) and a tram (23 mins to Schottentor, every 10-12 minutes) available nearby, but if you have to commute to the downtown and back several times a day as I did, traveling by car would save you a lot of time. There's also plenty of affordable parking garages available at the end of the route in the downtown, like those near the Votiv church and the Museum Quarter.
In this green neighborhood, there is a big park, an outdoor swimming pool, a few very decent restaurants, and other great places to explore if you're in the vacation mode. I will hopefully visit those next time I am here.
Huge thanks to Daniela!
