I stayed 6 weeks at the Supreme Studio Vienna Black. It is a very nice apartment with all the amenities you need. The bed is in a small niche and you have to crawl from the bottom into it. No problem for me but perhaps for some elderly person. The windows have nice shades and the AC is working nicely which is both important in summer. The infrastructure surrounding the apartment is fabulous. Grocery shopping, pharmacy, bank, clothing stores, restaurants and whatever you can think of are just around the corner as well as public transportation. Being close to tramway and metro is absolutely great.
