Henrik was most welcoming and helpful before we arrived. We needed an address to send a concert ticket to before our arrival and he was fine with us using his address (though in the end we didn't need it). He also let us leave our stuff in the apartment until later in the afternoon since there was no booking immediately following ours. The apartment was as described, calm, cosy, and very convenient in a fantastic area. It was a very good way to experience Berlin. A most pleasant stay!
