We stayed here for 5 nights with 4 people. The location is quite good, near all the good clubs, but you're a light sleeper, don't stay here as the KitKat club is literally right next door. We didn't mind the thumping bass at all hours too much, as we like to party ourselves! Kreuzberg is also within walking distance with all its nice cafés and restaurants. The apartment is very spacious with high ceilings, which was a welcome change for us after spending 6 nights in a hotel with rather small rooms. Bathrooms were clean, with clean towels and linen provided as indicated.
Unfortunately from the start we had a very gruff first interaction with Levan at the welcoming, as we were accidentally standing at the wrong entrance. And after checking in, we had requested extra bedlinen, as the provided ones are quite small but we were told "we had only paid for four people". This shows a lack of flexibility and hospitality.
Upon closer inspection we noticed very dirty areas on the floor (dust, hair etc.), though after communicating this with the host, a cleaning lady was sent within 2 hours to give the place another pass. This was very much appreciated. Also, the provided iron did not work, and they replaced it quite quickly, which we also appreciate a lot.
Though the apartment is large and spacious, it was very poorly equipped. Probably one of the most poorly equipped Airbnb's I have ever stayed at. Here's a non-exhaustive list of what we encountered: one medium and one small towel per person for the whole stay, tiny bed sheets, sunken in spring mattresses, limited kitchen tools and appliances (to the extent we had used Uber eats most of the time), spartan mostly basic IKEA furniture (understandable due to party nature of the city, but I'm comparing to other Airbnb's I've stayed at in the same price class), no brush to clean dishes.
Last, but in 2021 certainly not least, the WiFi barely worked at all. This was very unfortunate as we are all remote workers.
All that being said, if you adjust your expectations to the bare minimum you'll probably think this is a fine apartment for a short stay in Berlin. But again, considering the price range, we had expected more.
