We loved the apartment. It's a beautiful loft and super well located. An amazing veggie cafe nearby as well. Everything worked like a charm and the portable WiFi was super useful. On top of that Katharina was super responsive and was quick to respond to anything. We were a group of 7. The only thing I would comment on is that because we were traveling with my parents (who are older), the sleeping situation wasn't practical for us since at night they had to go to the bathroom often and the bathroom is close to one of the beds so, it would wake us up. Otherwise, a fantastic place and I highly, highly recommend it.
