We had the best stay at Lidas apartment! It was very clean, the bed was comfortable, the wifi worked (although not the fastest) and the apartment also had both iron and hairdryer, which wasn't mentioned in the description. You can hear trains passing by, but it didn't bother us. The location is fanstastic for access to public transportation, restaurants, shops and of course Mauerpark (Sundays!)! Lida was in touch with us before our trip and everything went well, regardless of us first having trouble reaching her friend Barbara (who let us in). We highly recommend Lida and her apartment!
