Thanks for in the info!
I stayed some time back at Baan Farang; and agree with the comment that you posted that it was a bit expensive, compared with other places I have stayed on the loop.
The other two suggestions are a bit out of my price range.
I found another place in Khun Yuam, Baan Sukjai, @300 per night; but it has gone down quite a bit and is not in good repair or well kept. I think they have also removed the place from Agoda, but it is still on Facebook.
Thanks again.
