The apartment is located at about 10 mn walk from Berlin Central train station, it is on the ground floor and directly on the side of a street.
There is light and a bit of rumbling noise coming from the street in the very first room, though it is a relatively quiet street.
The other room in the back is on the building yard side and is quiet, this is where we slept and had a peaceful and restful night.
The apartment is advertised as a two bedroom and I chose it on that basis. But actually it is not, it is a one bedroom. So I was disappointed in that.
Though on the whole we had a good stay and I guess for Berlin it is relatively well priced.
I think that this is a perfect flat for up to two people for a brief stay in Berlin.
