The apartment is very clean and modern. Space, lighting, and interior design are great. The kitchen is big, with lots of kitchenware and a variety of utensils, and there's a Billa supermarket just around the corner. So if you're a fan of cooking and making your own feel-at-home breakfasts and dinners (which I totally am) -- you'll very much enjoy your stay here. Otherwise, there are also plenty of restaurants and cafés within a walking distance, offering everything from street food to gourmet cuisine. With the city center being just 15 minutes away by bus or metro, you'll make it to many sights and shopping streets quickly and conveniently, which makes this apartment a perfect location for both short- and long-term stay. If you opt for the latter, be aware that there's an IKEA store, a huge shopping street (Mariahilfer Str.) and even a 50-meter Olympic swimming pool with sauna (Stadthallenbad) within a few tram stops. There are also a lot of hairdresser's saloons, pharmacies, and private medical labs in the neighborhood -- in one word, the location is great.
Some of the previous guests reported Wi-Fi issues in the apartment, and I'll share my experience. About a week before my coming, Petra installed a new Internet access point that derives Internet connection from mobile network (a SIM card, essentially). It worked totally fine for me, with an average speed of 10-12 Megabytes per second on my wireless devices, which is more than enough for most everyday tasks, both business and entertainment-wise. Please be aware that this access point gives you a choice of two WiFi networks -- one whose name includes 5G (at radiofrequency 5 GHz) and one whose name doesn't include it (at radiofrequency 2.4 GHz). I found the network without 5G to yield a more stable connection speed, probably because of the radiowave interference that its 5G counterpart experiences from neighboring WiFi routers. If you need even higher connection speeds for your laptop, you can connect it directly to the router by means an Ethernet cable (if you don't bring one with you, you can easily find it here at Mediamarkt or any nearby electronics store).
Overall, I'm very pleased with my stay and my communication with Petra, her father and his partner Gabi, who are always here to help. I will definitely stay here again if this apartment is available for the dates of my next trip. All the best to Petra and her family!
