We really enjoyed our stay at Ulf’s apartment. It was very clean, had everything we needed and the bed was SO comfortable - we finally got a few good nights of sleep we needed before holidays :) overall, I liked that there were a lot of very nice restaurants around (host provides you with tons of recommendations upon booking as well), but next time I would not go for Kreuzberg again, as it doesn’t feel 100% safe. You should know the area before you decide for it.
The warm water in the shower is enough for two people to have a quick, warm shower after one another, but it’s not enough for two long showers for sure. You need to wait until the water heats up in the boiler again.
Great stay overall, would recommend:)
