We stayed at the room for 2 nights. The room was very well designed, well equipped, and of higher quality than any other room or hotel I have stayed at during my travels around the world. The location was easily accessible with good transport links.
The entrance hallway to the room was still under construction during our stay; it can be startling to some especially arriving at night, however we were informed during booking and before arrival about this and experienced no issues. I have no doubt once all renovations are complete the place will be even better.
Simin & JP were very helpful throughout our stay and offered useful advice (we needed a place to store our luggage for half a day before leaving Vienna). We did not manage to meet them in person, however, speaking through the phone they were very friendly and welcoming.
