We had a wonderful stay at Jovana's. Everything about this place is great. The location is perfect, in a quiet neighborhood, but still with a lot of cafés and restaurants and only a couple of subway stations from the center.
The apartment itself has everything one needs. Two large bedrooms with double beds, one of them doubling as the living room. The kitchen is fully equipped. Finally, the hosts are extremely nice and welcoming. They are easy to communicate with and very quick to respond. They even gave us a lift from another location in Vienna to the apartment free of charge. Based on my experience with this apartment, I can only recommend it to anyone looking for accommodation in Vienna, and I will surely come back next time.
