I never met Kalu in person but communication with her was smooth and the apartment was like promised. You can go anywhere in the city from the apartment easily as the public connections are very good. The only thing that didn’t go well was the check-in the host had had to delegate to one of the neighbours who at first didn’t reply to my messages or calls for a long time after I arrived in Berlin. It had been agreed that I will inform when landed. I think that mistake won’t happen again, so I could definitely go to this same place again anyway.
