Booked the hotel as a transit point for a road trip across Vienna to Germany. The hotel provides free parking which was one of the criteria we selected it. The place was located in the northern park of the city, in a residential area which is a little more quiet than the tourist area. There are train stations and tram station close by, which is in walking distance. There are 3 supermarkets in walking distance and a selection of restaurants to pick including Mraz and Sohn which is a 2 star Michelin place.
We booked a full apartment for our group of 4 that includes 2 bedroom and a kitchen. There are heaters, but no aircon which made the summer Vienna a little hot, but bearable. Aircon is not common in European hotels so it is not uncommon. A small issue with the room is that there is only one toilet may not be adequate for 4 people during morning times.
The check-in process had not been the most smooth due to the limited hours that the check-in is open. However the hotel management has contacted our party earlier to explain how to deal with late check-in so it wasn't an issue. The staff there was friendly and explained about many attractions nearby. There is an additional cleaning fee and city tax that is collected separately which is stated in the terms, but may be surprising one did not read about the details. There is adequate parking space inside the premise, but the entrance can be a little small if you driving a larger car (e.g. SUV class).
