First room was dusty and had hair on the bed, so we changed room. There is no air conditioning, despite what they advertise, it was blowing out 29 degree heat all night and we couldn't sleep. I've seen other reviews with the same complaint, and staff confirmed A/C only works at certain times. The bed sinks in when you lay on it, and I ended up with a bad back.The toilet door doesn't close fully in any of the rooms, so you can hear eachother, and see eachother through the crack in the door. Hair drier didn't work, they replaced it with another one which would overheat and stop working after 30 seconds of use. Housekeeping came in and invaded our privacy when we left do not disturb on the door. They also never changed our sheets during our visit, they only made the bed. Breakfast was incredibly overpriced for what they offer, and it was always an unpleasant experience because of how busy and cramped it was. The location is in a really rough part of Vienna too, lots of drunk people. All in all, I would absolutely not recommend this hotel, particularly not for a couple.
