Katrins places was unbelievably clean. We had everything we needed for bathing, cooking, cleaning, provided to us in the studio apartment. The pullout sofa bed is comfortable! As newcomers to Berlin, the location was a bit inconvenient for us in a far corner of neukolln, but an S-bahn stop is only a 7 minute walk away to get back into the busier parts of the city. Check in and check out were very smooth. Would recommend this place for 2-4 travelers looking for a cheaper place and willing to travel the extra 10-15 minutes to get to places.
