Alexander and Bettina, living as they are next door to the place they rent out, are extremely helpful, always available but never intrusive. The apartment itself had every convenience item we could think of. The house is atmosperic, obviously part of an older Vienna, but completely rennovated, and the place had a good vibe to us. We couldn't wish for a better place or hosts. Some excellent local restaurants in the vicinity, easy walk to most of the main museums, the Belvedere practically next door, and both U-bahn and tram station (D route) within a short walk.
