This was a great place to stay! The location is good and the tram is about a 5-10 minute walk away. There's some good restaurants or cafes nearby, a whole indoor market, or the rest of the city at your finger tips! The window to the street can be noisy on Friday morning when the trucks pick up the glass recyclables.
The room is awesome though, it is ginormous! the bed is very comfortable and also ginormous. It's a share flat/apartment with 2 other bathrooms. Both have showers, but 1's shower gets water all over the floor if you position the doors wrong. Noise is pretty evident between rooms too but I never had much of an issue with it, it's nothing more or less than any other apartment in Europe.
The kitchen is great, the washer is also a dryer (located in the kitchen). I never even saw anyone else the 4 days we stayed there, I did hear others rustle about sometimes but never ran into anyone.
Overall I am very happy I chose this airbnb for my stay in Berlin!!
