I did not meet Walter. Instead, Thomas handled many details for the check in, and met us at the apartment for check in. I called Thomas when we arrived in Vienna, and he answered immediately. We made our way to the apartment, and he was waiting for us outside. Once inside, he made us coffee while he pointed out important sights, restaurants, and other highlights on a map. The introduction to Vienna was thorough. We enjoyed his humorous descriptions, and his expert insights into the city. Really, he was someone we should have had drinks with. I am sure he has some great stories. The apartment itself is very nice. My traveling companions and I appreciated the style of the furnishings, the kitchen, the bedrooms, and bathrooms. There is a separate toilet room and shower room, which were nice features for our traveling party of 4. The windows have power shades, which is great if you want to shut out light and sleep late. The apartment is a block or so from a subway entrance, and a short walk to several bus stops. The apartment is just off of Mariahilferstasse, which is a mostly pedestrian street lined with stores (jewelry, clothes, etc.). In addition, the hip cafe and bar filled Spittleberg is within walking distance, as is the city center. Overall, a really excellent place to stay. The only minor drawback is the tiny elevator, but that did not concern us much. I would definitely recommend this apartment.
