Katharina's place was very convenient and centrally located - we could easily walk to many memorials and attractions, and it was also just a 5-minute walk away from the closest train station. Upon arrival, Katharina personally checked us in and gave us some great recommendations for cafés nearby; communication with her was quick and easy. The space itself was clean and furnished in a minimalist style - this was a great stay and we'd definitely recommend it to other travellers to Berlin. Thank you!
