Luisa and Klaus's place is light, airy and comfortable. We were surprised by how easy it was to get around Vienna from there--an underground station is 30 ft away, tram lines around the corner, and walking into the centre was also very simple. Our teenage sons were able to manage the metro without us once or twice. So many little things proved easy. There is a grocery store across the street, recycling beside the building, and a park across the road. Thank you Luisa and Klaus!
