Karin's space was just what we were looking for. Check-in was easy (though we initially met and picked up the keys from Karin's daughter), and the space was large, private, and quiet. We had a tough time aligning schedules and didn't actually get to meet Karin until we were about to check out, though she was very responsive to messages and communicated well with us. The location in De Pijp was quiet at night and surrounded by awesome shops, bars, cafes, restaurants, and more.
I would highly recommend Karin's place and would definitely stay there again!
