Response from Elena:
Demands - not sure what demands Nathan is referring to as we did not even request the toilet seat to be fixed during our stay. I couldn't even sit on the toilet seat because it kept moving around.
Questions - Yes, I asked questions because Nathan's apartment was the first apartment I ever booked on airbnb and I was not familiar with the process of how to check in, etc.; which I even apologized ahead of time to Nathan and explained it was my first booking.
Messy - not sure what Nathan's definition of messy is but we made sure to throw away all trash and put the towels in the laundry basket, etc.
