Apart from myself, Lucy is the best host you could find. She was able to accommodate us at 6:00 in the morning, which never happened before.
The place is right beside Naschmarkt, 5 mins walk to golden saal, 10 mins walk to meseum quarter, seems to me no other location is a better location.
The place is spacious, equipped with everything you could think of; all in all there is not much more you could ask for.
