I arrived early - around 9:30a and Jan was there to greet me and let me in to the apartment (I even stayed until around noon on the day I left) - a big perk vs. staying in a hotel! Everything was clean and ready to go as soon as we arrived.
Location wise, it's outside of downtown but right between two main train stations, so it was easy to get into the Marienplatz area (about 15 mins door to door; or walking was about 30 mins). Seems like it is SUPER close to any Octoberfest celebrations though
The WiFi stopped working on the 2nd day (I think it just had to be reset), which was a bummer. Overall though, the place was great and so was Jan.
