Daniela's apartment is really great, it is sparkling clean, perfectly located in the middle of everything, yet it was very quiet at night. The bed was very comfortable and although we did not use the kitchen very much, it looked like you would have everything necessary for cooking. The only thing that was a bit tricky for us, was the in-person check in (as opposed to self check in, which I find more convenient), and giving an exact time for key handing. But it's really a small detail, and I highly recommend this place if you're visiting Vienna!
