Keori's room is pretty much like in the pictures. I took the 108 bus from the airport and it drops you off 10 minutes walking to Keori's place, you just walk one street straight.
You don't get a key and you do have to call Keori to his cell to access the place but this was no problem, he was always available so don't worry about that, just make sure you have a phone with calls if you are an international traveler.
The place doesn't have WiFi but Keori shared data from his phone so that solves simple Internet tasks like email.
The place is 420 friendly and the living room did smell like it although the room was perfectly fine with no smoke.
