Pros:
Stephan reached out before our arrival and provided the details on whom would we meet and when. Shortly after arriving, we were met by Martha who whisked us into our room. Excellent location! Just across the state opera house. It is in between the Karlsplatz and Stephanplatz train stations. Fast Wi-Fi speed, approximately 20mbps download and 3-4 mbps upload. There is a Eurospar (grocery store) about 5 minutes (walking) away, which is very convenient. There were a couple of power plug adapters and a European 4-port outlet power strip for all of your charging/power needs. There were plenty of towels available and the bathroom was very clean. My girlfriend notes it is very pretty inside the apartment.

Cons:
The electric water heater should have a little sticker on it, if the flame is not lit inside, you need to rotate the left knob to the left to the capital R for a few seconds, then you will have warm water shortly thereafter. While the room is on the second to highest floor, each morning and night there were chairs shuffling on the floor above; however, Stefan has a spare fan in the closet to help drown out the noise which did the trick in case you are a light sleeper.
