This is my first time staying in Vienna. The hotel was good and comfortable. My room was in 9F and I could see the river from the window. It was really good and romtatic. However, the toilet was not perfect clean, I saw some dirty in the there and I used the toilet brush to clean it to avoid my wife getting crazy. And the location was not easy to find for me. I was using google map to find the hotel, and google map guide me to entrance a underground which will lost your GPS signal. Therefore, I took some time to find the hotel. I suggest you search DC tower instead of hotel in your GPS. And the fee of parking lot was really expensive, it takes 30 Europe per day. I was thinking about parking on the road side for free. But I couldn’t find a closed parking space. And I was in bad luck, I lost my ticket. I spent 60 Europe for ticket lost.
