I'd like to clarify that me leaving the lights on was an oversight and I'd like to apologize for that.
What makes more sense:
A - Leaving bathroom lights on as an oversight
B - Deliberately leaving the lights on, only in one small division in a huge apartment as retaliation.
The rest of the review, regarding the retaliation due to not getting a refund is false. I left the apartment 3 days before any exchange of messages regarding a possible refund even occurred!
If any future hosts/guests would like to know more about what happened, I will be happy to explain my side of this story.
