The location was excellent between two metros stations; each about 6 minutes walk. Very close to museums, bars, restaurants and shops.
The buffet breakfast (7-10 am daily) was simple but good - bread rolls with cheese or ham and butter; cornflakes, muesli, yogurt, tinned fruit, tea, coffee, juice and water.
The room was comfortable and very quiet at night. Fairly spacious with two arm chairs but no fridge or kettle. It was clean and cleaned daily.
Free excellent wifi (as everywhere in Vienna).
