Didn't meet Irina but did meet her roommate Gregory. I made the booking less than 24 hours in advance (it was approved by Irina ~10 hours before I arrived), and Gregory was not expecting visitors but was very friendly and accommodating and got the room set up for us. I was pretty disoriented by the situation for a few minutes before realizing that Gregory is blind! The surrounding area is a little sketchy, but I felt safe at this airbnb.
