Katharina's place is well equipped and comfortable for 2 people. It was clean and tidy. The kitchen is small, but we found everything that we needed for cooking. I managed to cook several complete meals in there. The cookware is actually pretty nice and in good order. Coffee is also provided via a nescafe machine, which is nice and leaves no mess to clean. Parking was super easy with plenty of street parking on this block. The AC gave us a very welcome break from the intense heat this week. The location is nice with lots of amenities close by. Grocery, cafe, bars, restaraunts, ice cream shops are all within 5 min walk. Public transport is super easy from here, also. We just kept the car parked and used the tram and U-bahn.
It is only a 4 star review because the living area could include a comfy chair instead of just the small sofa. There is plenty of room for it. My wife wanted a quick nap on the sofa leaving me nowhere to sit except the dining table. And there was an annoying issue with the cleaning lady. The owner has apologized and all is well, but it was a very awkward situation.
Overall a good stay and we will come again hopefully next year and stay here again.
