The hosts were quickly responsive to all communications with helpful information. The apartment is very well kept, very clean, very spacious with lots of bedroom, living room, entrance, and kitchen space for a family or group staying together. The location is very convenient to local activities with a short walk and to the Karlsplatz connection for traveling farther with the public transportation. Two grocery stores are just one block away for stocking up at the apartment, and restaurants and nightlife are very close. Many museums and sights are within easy walking distance. The mobile wifi hotspot is very useful if you do not have a local data / calling plan.
