Location location location! I stayed at Alexandra’s place in December 2019 on a long weekend. If you are a single traveller, the best place to stay in Vienna is here. The shops, all coffeehouses and restaurants are in 2-3 minutes walking distance. Although being in the middle of the city, the place is very quiet, very clean and a tidy nice apartment. It is used as an office during the weekday, however the place is yours in the evenings and on the weekends. I highly recommend this place. Very warm welcome and hospitability in cold weather!
