Astrid was very polite and efficient, showed me around the place and provided some tips on museums to see. The locations is very good - walking distance to the city center, the museums, and some really nice cafes, especially the Naschtmarkt. The place was as described. The room was a bit small and space that could be used for the guests stuff on countertops was taken up by knick-knacks. An extra power outlet would be nice as well.
