Kristof's studio was lovely, right in front of the opera. The neighbourhood is quiet but still very central. There is a lot to see and do nearby. I struggled a bit to climb to the last floor, where the studio is located, with my luggage. I haven't met Kristof but he was very friendly in his messages. He let me drop my luggage off before I checked-in and after I checked-out which made my life a lot easier! My stay was very good!
