Fred and Rita have been friendly ans helpful. Rita came to pick us up at the train station to take the suitcases by car, because the station is about 10 minutes walk. She also brought us to the supermarket upon arrival.
The house is correct, adequate temperature and cozy house. But we have missed a sofa in the living room where we can rest, the wifi has not worked well by not letting connect several devices, nor do we find a broom to be able to sweep when we leave.
It is somewhat far from the center of Berlin, but in a quiet residential area.
