This was a great place to stay and I'd definitely return. The hotel is in a good spot in Kreuzberg next to tons of great bars and restaurants; there are plenty of museums and landmarks within walking or biking distance, and a few metro stations nearby.
My room was really big and clean, as was the bathroom; the big windows were helpful with the breeze and the fans kept the room from being too hot. The man at the front desk was incredibly friendly and helpful, making it easy to check in as well as arranging an early-morning taxi to the airport for me when I was leaving.
