The check-in went smoothly even if we were late. The staff actually called to remind us to check in online. The place was easy to find, and close to restaurants, tram, and subway. It was actually walking distance to sites. The only thing is the noise at night. It is situated in a very busy area and you can hear the voices of people having fun outside, tram, police siren, etc. We didn’t mind though because we fell asleep easily after doing a lot of walking in Berlin. And also, no parking spot. We had to go to the Decathlon parking spot in Alexanderplatz to park our car for 2 days (by the way, you need exact change to pay for parking)…. Will recommend
