Funky and edgy; just what you would expect from Berlin. Erich is an attentive host; always available. The flat has a few quirks that make it more suitable for the adventurous traveller than one looking for comfort (it's on the 4th floor, no lift; the bathroom is very small and in the neighbouring flat; the ceiling is low (just okay for a 1.8m/6ft tall person)... but the space is unique so fun and the location excellent.
