We stayed here in June 2009 during our 3-day trip to Vienna. Had a triple and double room. It turned out, both rooms were triple rooms. On the positive side, rooms are bright, airy and very spacious. The bathroom is tiny, and the room has a dressing room/walk-in closet larger than the bathroom. Not a smart use of the space, if you ask me. The rooms are in general clean, but after checking in, I discovered a pair of black panties hanging in the dressing room - not a good sign. The bathrooms are really small, some have full bathtubs, some only 1/2 bathtubs. The toiletries are very basic - solid soap and shower gel in super-small portions.
Overall, the rooms have a 70's look and while clean, they look pretty aged. The doors are probably as old as me :) - but not "antique old", just "stale old." The curtains didn't seem clean, had holes in them (cigarettes?) and seemed to have been used to kill flies or other insects (sorry for being graphic...). I don't think any of the rooms are non-smoking, but our room didn't have any cigarette odor, while our kids' room had. The hallways are dingy, with strange copper-looking covers on top of the ceiling and they were in general used to store extra beds, housekeeping carts, etc. The carpets in the room seemed clean, albeit old, while the rugs in the lobby looked tired and not cleaned professionally in a while. There is a parrot in the lobby which my kids found amusing - I personally didn't like that his dirt kept falling on some newspapers on the floor.
We didn't try the breakfast as for the 7 euro price per person we all ate croissants and had coffee at the coffee shop in front of the hotel. The parking is pricey (15 euro+ per day in the garage), but if you're lucky to find a spot on the street where the parking entrance is located, you don't pay a dime. The staff is friendly, but can be clueless about most things. E.g., we were told a 13 y.o. would need to pay adult fare on the subway, whereas 6-15 y.o. only pay 1/2 price. Feel free to ask them for information, but double check just in case. The hotel has wireless internet, but pretty poor quality (frequent connection drops).
The hotel is perfectly located next to Schonbrunn Palace and 7 stops on the subway from Karlsplatz. Vienna is a great city and we will definitely return to visit, just not at this hotel - unless it is renovated!
