No WiFi in this apartment, which wouldn’t be a huge issue but cell service was also very weak as the place is in the basement. Being able to check-in at any time was a huge plus for us, and the place was clean and looked as-advertised, no complaints whatsoever about check-in or the condition of the apartment. A bit far from central Berlin and not many grocery stores locally if you wanted to cook dinner in, but several restaurants nearby and very easy to access the U-Bahn. Overall a great place to stay!
