The apartment is well situated steps from Karlsplatz — this is the best part of the flat — and very easy to get around Vienna either on foot or through transit.
Eva & co provided quick (if sometimes curt) responses — and also provided tips for the area, which were appreciated.
Some small parts of the flat need a tiny bit of upkeep — but otherwise the flat is thoughtfully appointed to provide everything you would need for a short stay (dish washer, great water pressure in the shower, laundry room with machine, etc.)
