Kiki is a gracious host. She was flexible with my uncertain check-in time, explained the essentials, and remained responsive throughout. The area does not compare to the city center, but I never felt unsafe. I would just mention two things to keep in mind:
(1) The front door to the building is rather difficult to open. Kiki has said that this is beyond her control due to the collective owner's decision
(2) I don't believe I saw this in her booking info, but you will likely be asked to provide a full ID number as part of her compliance with local tax law. Many guests in Europe will not be surprised by this, but I figured I would mention for those who might not be used to this.
