Ingeborg is very friendly and although she doesn't speak English, we were able to communicate with gestures and Google translate. The location is quiet, but a regular bus service (200 and 156) is a 3 minute walk away and provides an excellent connection to the tram and S Bahn and U Bahn networks. The accommodation is exclusive use of a the upstairs and includes the bedroom sitting and dining areas and en-suite toilet and wash basin.
The shower is in the basement which means passing through shared areas, but this wasn't a problem as Ingeborg respects her visitor's privacy. Value for money is excellent and I look forward to staying again next time I visit Berlin.
