"I am a logistics man and therefore, the best location you can get in Vienna to keep routes short and get to the spots easily, fast, cheap, and reliably. Just opposite the CAT/Commuter Rail terminal from/to the airport, you need only to walk across the street. The good: you can check in your bags for most flights at the CAT Terminal, and you can travel to the airport without bags. It works perfectly: book a later flight, check in your bags, and discover Vienna until your flight leaves. From here, you are connected by subway/underground/metro to all major spots in the city: Stephansplatz, the Museums District, or Schönbrunn Palace. Back to the hotel. We booked a room, which sounds more like a suite with two bedrooms and bathrooms. But we found out it was a connecting room, which the reservation system lists as a single accommodation. The room was nice. We were glad not to stay there on a weekday because you face the bank's boardroom from your window. The rooms were nice and clean, and as requested, we got one with a twin configuration and the other with a queen-size bed. We also booked a limited (and it is worth it!!!) surcharge for access to the Executive Lounge. Besides Happy Hour and Breakfast, which you can have during the opening hours: a wonderful roof terrace - an oasis of tranquillity with a great view above the city park. There was also a small mix-up with the keycards: we got more for the single room but for the twin room. But Christian solved it in the Austrian way: with a smile, with friendliness, and with the Viennese Charm which let you forget every kind of trouble, great and small. We had tickets for The Phantom of the Opera and a table reservation right next to the theatre, so I could not take advantage of the Happy Hour as much as I normally would. I went to the buffet a few times and discovered my favorite Austrian bakery item: a so-called "Salzstange," a white roll shaped like a croissant (but not fluffy) with salt crystals and caraway. This piece is just a vacation in Austria in my childhood. Every time I went to the buffet, those were gone first, and at the time, I wanted to ask, " Our driver arrived. So I decided to have one for breakfast the next morning. Unfortunately, it was very disappointing: they do not have them as a breakfast item. Tetjana noticed that I was somehow sad, and she asked. I told her that I was disappointed and needed to find an open bakery to buy some. She went straight to the main restaurant and got me some. I was so excited. After check-out (also very friendly), we left our cabin baggage with the bell captain. When I returned, the bell captain's desk was not attended. I noticed one man explaining something to two other ladies on their mobile phones. This man never turned around, so I thought it might be a guest. So, there was no sign that he was the bell captain, and he lost eye contact with his counter. I was not alone, with a receipt in hand, waiting for someone to handle the return requests. At that moment, a young female front-desk agent came out of the back office and immediately saw the guests waiting for their baggage, while there were no other guests in the check-in queue. She walked immediately over to pick up the tickets and hand over our bags. The bell captain noticed now several guests waiting for his attention and said, "One more minute" (something you do not want to hear when you have already waited for some time). It is good to help guests who need assistance, even if it is not their original responsibility. When there are no other guests, it's better than standing around. The problem was that if their original function went unaddressed and they did not notice, it became challenging to resolve individual problems on guests' smartphones. You need to be smart enough to call someone else to help the ladies with their smartphones or the other guests who need their bags. In this case, it was ok, since I did not miss the next airport express, and the other agent came out (17:30 hrs - right-most counter at the front desk. I had no chance to read her nametag, and she saw that new guests had arrived at the check-in, so she would miss helping them, which was her original job. So 99/100, and next time I would use the baggage locker at the CAT terminal for greater independence in baggage collection. This was the only exception - but as said: the unnamed front desk agent deserved for her action to be mentioned. And such a thing happens, but it will not keep me away from booking this hotel again. Thanks again to Christian, Tetjana, and the helpful front-desk agent; I didn't catch her name."
