Lovely apartment in a great location! Very close to public transportation (bus, U-bahn), lots of restaurants/cafes and grocery stores in walking distance, and quiet neighborhood.
The host replied quickly to my questions and was very accommodating and flexible with check-in. I originally asked if I could drop off my bags early, which he allowed; unfortunately my flight was delayed so I arrived much later than expected but he was very flexible.
Thank you for a great stay in Berlin!
