The apartment was as described and advertised, very lovely place and location, literally 1 minute to the ubahn, Olga and her colleagues were very helpful and were very quick to get any issues fixed. I would highly recommend staying at their apartment, anyone would certainly not be disappointed. There's also a small washing machine in the bathroom which works very well, we haven't found many faults with the apartment, there's also a choice of 3 supermarkets to use (lidl, netto and rewe). We would definitely stay here again if we return to Berlin.
