The accommodation is very clean and tidy and is in a fantastic location only a 1 minute walk from subway trains, trams and all shops you need. Very central location means all tourist attractions are only a few stops away by train. Klaus is a very sociable and easy going host who speaks perfect English (for non German speakers). He has an excellent knowledge of Berlin and it's interesting history and can make eccellent recommendations for sightseeing, eating and drinking. His communication before arrival was first class with clear instructions for things you need and how to find his appartment. Would definitely recommend a stay here and I will definitely be looking to rebook on my next visit to this wonderful city.
