Procedure of getting Education visa is long, up to 1.5 month. Try to explore process of getting and you will understand why they all asked you 50K for help.
you can book something outside with limitation (I never used) or use their advertisment at Line about some Thai food or something like pizza. For me I was full after every meal. And of course no alcohol...
Yes , I was there till February 14. An ordinary hotel. Any payment available. Not new. Not far from Don Mueang. Clean room with two bed, kitchen zone, TV, unlimited pure water. Sometimes the smell of sewage from the ventilation. Pre-order food in boxes. No exit to balcone. The view from the window is uninteresting, street. The so-called pre-order walks - after the first test. There is a relaxation area. Communication with stuff via telephone or Line. At the exit you receive a health certificate and you will be ordered a taxi to the airport. My opinion is 4 with minus out of 5.
