First, here's what we liked. The location is central near the Museum Quarter, the Kunsthistoriches Museum, Natural History Museum, Hofburg Treasury and the State Opera. There is also a City Bike Wien station and grocery store extremely close to the unit that make it easy to get a bike and obtain groceries. Internet was extremely fast; 60Mbps. Lots of space to hang out in and enjoy; well equipped kitchen with working dishwasher. Lots of storage available for your bags. Olga's associate Erich met us at a convenient time and was there waiting for us upon arrival.

Here is what could have been improved. No shampoo, conditioner or bar soap are provided, so bring your own. If you needs sheets for more than 2 beds, bring your own, as sheets are only provided for 2 beds even when we booked 3 people in the unit. No hand towels or wash clothes are provided; large bath towels were all that was available, so bring your own if that's important. There was no welcome message from the host after booking the unit; I had to follow-up about our arrival. There was also no welcome letter or information on the city included inside the unit, as other hosts often provide. Olga's associate Erich dropped by towels and sheets the last day and was gone in 30 seconds with nothing more than "hello," when a "how was your stay" at a minimum could have been offered.
