Not a guest house!
It's just a room in an old apartment building. There is no reception, just a woman who meets you outside to show you to the room and then ask you for a 500 baht deposit.
ข้อดี: The woman's effort to put the room on Expedia to make money.
ข้อเสีย: Learn about the meaning of "guest house".
ที่ตั้ง: It reminded us of the new Judge Dredd movie. We felt like we were the main characters. It was scary.
