The kitchen was fully stocked for us to cook 2-3 meals a day, the couch was comfortable enough to sit on and very comfortable to sleep on. The bed however could use a 2-4cm foam topper as it was very firm. The bathroom, while small, was fully functional and the combo washer dryer allowed us to pack half the clothes we would normally need as we washed them all halfway through our stay. There was also a very large foldable drying rack that came in handy for most of our stay. The back pavilion is a nice tranquil and private-ish place to lounge with a bottle of wine or the balcony to the apartment works well too. The wifi worked well for most of our trip, though it faltered at one point but a quick call to the host helped us reset it within 10 minutes. The place felt safe and secure.
I will add that if you plan on sleeping with the windows open, you will need earplugs as the cars and buses seem to go non-stop throughout the night. If however you close the windows the insulation is amazing and you can barely hear the outside world at all.
I came here for a business trip that I brought my wife along for and overall it was a very nice stay. There are two grocery stores in decent walking distance and a café and meat/butcher shop practically next door (maybe 50 meters down the street). 2 different U-Bahns were in good walking distance too plus if you wanted to take the bus there was a bus stop right out front. And the beirgarten was amazingly close and their food and drink was some of the best I had all week.
I would definitely recommend this place for others to visit, but maybe not in the middle of August as the air conditioning was actually a passive cooling system and while it did keep the place cool in the morning it could not keep up with the 95F / 32C temperatures that we endured while we were there.
