Bed bugs and mouldy smelly rooms - read till the end

We booked Jinda's because of a special offer on Agoda for a double room. We wanted to stay close to the night life/beach at Ao Nang and indeed the place it is really central. We checked in and we discovered that the room was with a shared bathroom. We went to check and the room was with a supersmall window on a corridor and the shared bathroom was old and really dirty. so we paid 4 euros more to upgrade to a room with private bathroom.
arrived in the room you can smell how old and humid the room is. the curtains are covered by mold (which you visibly see). The view is ruined by the trash underneath that smells bad with two dead pigeons. The bathroom was disgusting and we were afraid to touch the walls or walking with no shoes to get something.

With a bus at 7 in the morning we decided to go over it and we went out. We came back (btw the place stays always open and has no reception in the night so everyone can enter) and once in bed we notice small black dots. After we took sever pictures with macrolens we noticed that were bugs!!

They were everywhere, from pillows to sheets and towels.
we called Jinda and after 20 minutes she arrived and she was at the beginning a bit defensive but she then realized how serious the problem was and she gave our money back. at 1 in the night we started looking for another hotel to stay with.

travellers, stay away from this place! better spend few euros more than deal with things that can bother your trip (the lesson we learned)

P.s. ALL THE ROOMS ARE LIKE THAT ONE! I forgot to mention that before to give our money back she invited to change room saying that was better. Same problem looking carefully at the bed sheets. After that she refund us.
