Hat Yai is a bit wired town with hundreds of different hotels,most of them are really old,pricy and...empty!
So we left kilometers behind looking for a cheep but acceptable hotel for transit night and finally came back to Laem Thong Hotel,located within 300 meters(!) from Hat Yai railway station,very close.
We took a 380 bath double room with fan. And we came back to 70's! Very old furniture,smoked, with specific smell..actually I was afraid of mice and insects,but no one appeared) There was a window,but overlooking the wall and tighty closed with dark curtain - so,there was no window in the room) The bed was ok, covered with sheet, with 2 pillows and kind of big towel instead of dovet.The TV was working, with 3 english speaking channels. The bathroom was quite spacious,clean,tile faced,with hot water. No personal cosmetic accessorise. No safe deposit. Wifi was good both in the room and lobby. For 50 bath there's tasty thai food,big portions,but mice a running under the tables..)
To sleep 1 night and to take a shower this place is ok,but to be honest,I was looking forward to leave it.
