I stayed in the larger suite which had ample room and large windows. Also equipped with clothes washer, iron, bathrobes, comfortable bedding, kitchenette, thoughtful extras like voltage adapter.
The location is beyond good. Walk out your door to a great Italian pizza/pasta cafe, the best shopping and dining in Vienna. Super close to churches, museums, concert halls, everything. Owner super with communication. Air conditioning didn't seem to work all that well, but it was comfortable. I have stayed at the Steinberger which is just a block away (great hotel),but I will prefer to stay here again in the future.
