I stayed here for 2 nights. I arrived late around 12 pm. they guy a reception was there and waiting for me. The bed was comfortable, there was privacy curtain. There is a universal power plug at each bed together with locker (below the bed). They provide towel as well. The WC was clean but a little too small. The shower area was spacious though and they do have hot shower. They do not have minivan to airport and they do not no contact number to rent motorbike. The good news is, it is close to Lee Garden and the morning market and the clock tower, so walking is possible. The ASEAN Bazaar is a little far, 2km, possible walking but can use Grab as well.
The internet connection was good both at dorm and reception. They have a kitchen area as well.
Though it is good, but I think there are other places which can offer a better value (though I am not sure if backpackers hostel in HatYai is probably all like this). The staff could be more friendlier and helpful too.
Overall ok place.
