Charlotte's flat is well located in an exciting spot in Kreuzberg. The flat is clean, spacious, and comfortable. Lots of light. Charlotte and Martina were very accommodating and helpful--Martina gave me some tips on a gym and yoga studio, and Charlotte printed out a train ticket for me. The neighborhood is full of life. A beautiful cafe around the corner, and then many eclectic shops, lounges, and restaurants. Two train stations are close, but Berlin's a walk-able city so I rarely took the trains. There's a park nearby and a wonderful movie house down the block--the outside of it is urban rough and the theaters are great. Wonderful sound and projection. All in all, a comfortable flat in a rich and diverse neighborhood. I recommend!
