We had a very comfortable stay here while we were at Vienna. First off, its located very conveniently, a brief tram ride away from most attractions, with tram stops just outside the apartment. There was an outdoor music festival going on within a ten minute walk from the apartment that we enjoyed each night. If you like to cook, the supermarket is just minutes away and the apartment was well stocked with pans, pots and other utensils.
The host Felix was very helpful letting us check in early and provided us some pointers on local cafes and restaurants nearby.
