I was very impressed by the quick responses from both Boris and Andreas when I was confused on check-in night (totally my fault for not checking airbnb for check-in instructions more detailed than contained in the initial confirmation).
This place is just as described. Its a perfect place with solid amenities. (I was able to do a little quick laundry mid-stay which was a big bonus). I didn't hear any construction noise at all during my stage as another review briefly mentioned, so that work must be complete.
The place is a solidly built, updated classic building (Entry doors are huge and its easy to imagine the owners in late 19th century pulling their carriage in through the passageway into the buildings courtyard). The cooling/heating may take a little time to change because of the thermal mass of the place and radiant heating, but I had zero issue with it. (It was very toasty warm when I arrived. I like it a little cooler, and after some hours I was able to get it to perfect temp. that stayed solid for my whole stay).
The added touches of an espresso maker, dishwasher and supplies where a nice bonus.
Its location is fantastic. 'just a block or two away from a train/uBahn station; I was able to get around town quickly. Groceries, restaurants, pharmacies are very near.
