Ivos was a wonderful host the whole time--super responsive before, during, and after the trip, with wonderful tips on what to do in Berlin. The apartment's location is amazing: a great place to walk just about anywhere in Berlin (or take a quick train ride) and super safe even coming back very late at night. It's also just an amazing view, so even when I was doing work in the apartment, I didn't feel like I was missing out on Berlin. I recommend this place--and Ivos--enthusiastically!
