Well, if you want to visit Mae Sai, this is probably one of the better choices, but if you don't absolutely need to stay, DON'T.
The reason they get rated as a two, is because their staff do their best with obviously limited support from owners/management.
As a whole, it's run down, it's filthy, and from a safety perspective it's a death trap. Loose wires everywhere, char marks from shorts on the electric outlets, and much more.
Pretty rare I write a negative review, but this place has earned it!
