Things we loved about our stay:
* Jan is a wonderful host and was very accommodating with our check-in time, greeted us with a carafe of mint-infused water, and made sure we were familiar with some of the quirky functional things in the apartment before he left.
* Beds are very comfortable, water pressure is good, you can drink water straight from the tap (big $ saver by being able to refill our bottles every day before going out), elevator to the second floor location was great for checking in/out with suitcases, it was great to be able to open the door to the tiny patio with herbs and flowers and listen to the neighborhood sounds while enjoying coffee/breakfast in the mornings.
* The location is fantastic! It was a 5-min walk to the train, which was only a single stop from the main station on one set of lines, and a single stop from the Marienplatz on another set of lines.
* Do yourself a favor, and be sure to take in a meal at Andy's Krablergarten around the corner (between the flat and the train station). It is AMAZING. Make sure you are insanely hungry - the portions are huge, take cash (no cards accepted), and count on having leftovers the next day (not sure how it is possible, but the food tasted even better than the night before).
One note of consideration:
There is a beer garden in the backyard (Andy's Krablergarten) and a bar next door - which is wonderfully convenient for many, but which did generate a bit of noise at night. Granted, I'm sure this is not nearly as much of an issue during the cooler months (other than maybe when people leave the bars upon closing at 2am)! Ideally, I would have simply gone and joined in the fun, but I was traveling with my young nephew and didn't have that option on this particular trip. :)
Overall, a wonderful flat to call "home" as you explore the city!
