Definitely recommend this Airbnb if you need an apartment for a group! Clean, multiple bathrooms, good wifi, heat, and hot water was plentiful. Although it is a little farther from the city center, if it is a very close walk to the metro - maybe 8 minutes? (and any closer to the center was too expensive for my group's budget). There was only one other room occupied while we were there, and although they were awake longer than my friends and I, we barely noticed, which is nice to know it's not too loud. Check in was a little difficult because we didn't speak any German, but in the end, the woman next door figured out what I was saying. Check out was super easy. Overall, we enjoyed our stay in Berlin!
