My wife and I rented this apartment for a three day stay in Vienna. It was amazing. The photos do not do this place justice; it is large, beautiful, and comfortable. The bedroom is larger than many living rooms and the nine foot ceiling (maybe taller) really helped the space breathe. The bathroom is also enormous and beautiful, with a generous sized bathtub and shower. (One word of caution - the hot water tap on the sink seems to take priority over the shower, so don't try to shave while your wife is trying to shower or you will get yelled at!)
It is located in a courtyard inside of one of the beautiful old stone buildings near the college campus in Vienna. It was very quiet at night. As the ad explains, there are plenty of more "creative" uses of the space if you have the time, but don't overlook how great this place is even if you're not planning to use the toys.
Our stop here was one of many during our travels throughout Bavaria and Austria, and this was the nicest AirBNB we stopped at by a large margin. Also, and this might be specific to the time of year (2022 heat wave) or our own preferences, we had purchased a small fan and carried it around with us since many of the places we stayed had no air conditioning or fans of our own. I can say that the large size of the bedroom plus our little fan made it very cool and helped with a lot of circulation. We found other rooms somewhat stuffy, but not this one.
There is a coffee shop literally next door, a small grocery two doors down, and a tram stop right around the corner. You can get to the major museums, landmarks, or train station in about 30 minutes or so. Google Maps has no problem navigating the city, so it's very easy to get around.
Because the college campus is close by, there are lots of fun places for food and drink late into the night in a more casual atmosphere from the classier places downtown. I would highly recommend the goulash and spatzl from Centimeter a few tram stops down the line for a late night snack, or the outdoor beirgartens in the college campus itself for an outdoor weisbeer.
Overall fantastic. I will definitely be looking for Sophie's rentals next time I'm in Vienna.
