The patient wards in Samui hospital (and most govt hospitals) have many patients, are open air, mosquitos in the evening, not clean, and in Samui there were cats and dogs in the hospital as well. I was ok with that part, but the rest was not really ok.
The patient's family or friends sleep on mats on the floor and are expected to stay with the patient at all times.
A private room at the time (2017) only cost 2000 baht per night, so it was worth it.
