Great place for Vienna trip, about 10 mins of walk from the main train station. Grocery stores are within 5 mins of walking. Bus and tram stations are within 7-10 mins of walking as well. Oh, the Belvedere is also within walking distance as well.
Check in and out was nice and easy. Clear instructions was given by the host to reach the apartment. And provided detailed explanations on living in the apartment, places to go nearby, and gave us a list of great suggestions to tour in Vienna.
The apartment itself is gorgeous - clean, spacious, great amenities. Bed was comfy, and the kitchen was great that we cooked a couple breakfast and dinner. Definitely worth the price we had. We highly recommend this apartment to Vienna travelers.
