They were great hosts - met us at the apartment to walk us through things and made sure we understood all the rules and requirements. The apartment itself is lovely - a good size, clean, and on a quiet block but within easy reach of a grocery store and several good restaurant options. The kitchen is small, but we were able to cook without too much trouble. It was very easy to get to public transportation and access everything we wanted to see in Vienna. The wifi was strong and consistent!
