We recently stayed here for one night which is enough. We booked in advance but when we arrived, the women on reception couldn't even understand "we have a booking". She just offered us a room as if we had just walked in off the street. The room was much cheaper if you just turn up by the way. After a lot of hand gestures, writing things down, she finally realised that I had a booking yet she never looked in the book or on the computer yet she demanded another 200baht since I booked online. I refused and stuck with the 450 baht you pay without a booking.
I came down a bit later to ask a question and her reaction was to slam the mouse down she was using to navigate through Facebook and then let off a huge sigh. I walked out without an answer.
It is ok for one night maximum as long as you don't go with a booking and you don't ask any questions. The location is also really good. Just make sure you leave the bus station the rightwy, that area can be a little confusing.
Also, the wifi never worked. Not a biggy but might be for others.More
