What a perfect place for my week long stay in Vienna and what lovely people! I didn't try the out-of-tune piano but everything else was 110% completely-in-tune: from Klaus meeting me at the metro; his tips and maps; and the warm hospitality of the entire family. The room is massive AND it has its own dressing room and desk. The bed is super comfy and the kitchen is way cool. It's easy to find, close to everything - from transit to countless great places to eat, shop and sightsee. I would absolutely stay here again. Thank you all for making me feel so welcome.
