Good place to stay for a few days in Berlin. Enough room for 4 and a nice atmosphere. We loved the retro-style and vinyl discs with good old music!
The apartment is on the ground floor in a quite busy street, you actually sleep a few meters away from the traffic. But the traffic is less during the night and closing down the schutters helpt a lot, so we did sleep well enough.
Good restaurant next door for breakfast.
