We had a pleasant stay in Antonio's apartment which is spacious and well located. His cleaner meets guests Mon -Fri, but as we arrived Sat afternoon we collected the keys from a shop nearby - unusual but it worked fine. The apartment is maybe a little less impressive than in the photos (furniture is quite basic, and kitchen a bit dated), but it was very clean and the area was perfect for us as it is located to the west in the Museum Quarter (very nice) and is just 15 mins' walk to the Wiener Stadthalle where we were going to a gig. Just to note that as the local shops close Saturday afternoon and don't reopen until Monday we were unable to buy basic breakfast provisions or even toiletries (only a liquid handsoap was provided), so future visitors should be aware of this.
