Stayed with my wife for a few nights while touring the Wachau/Krems/Kamptal/Langenlois area. Easy to get to by car and well situated in the middle of things. A car is strongly suggested for wine area touring, though. Service was up to standard and beyond. Most friendly staff I've seen in Austria. We got upgraded to a larger room just "because it was free" for those nights - spectacular service! The house is in good condition, facilities are great. The pool, vineyards, family made great wine, mostly organic local breakfast - superb. Wi-Fi was (for the first time) fast and completely included.
If we are in the area again in the future with kids, this would be our first and only choice. The amount of things they have for kids there is impressive - trampoline, slackline, all sorts of outdoor toys and swings - all within a house/summer cottage type of atmosphere. Not a busy hotel atmosphere, which was a major plus in our books.
