Katharina has been a great accomodating host, communication was effective and her room spotless! The flat is really sunny and the room quite big, the whole of it (bathroom included) basically recently furnished. The neighborhood area is quiet but we could reach everything easily on foot (there's also an Aldi and a Lidl right in front of that very building). Just keep in consideration that the room is on the last floor and there is no lift. Would definitely consider it again if coming back to Berlin!
