Welcome to the forum. You don't just have to rely on Dutch expats. There is a lot of knowledge available to you on this forum, and that knowledge is provided by a variety of nationalities.
Just ask away - I'm sure you'll be impressed with the quality of the feedback.
Hi Akwa and welcome. Nice to see folks who haven't been put off by recent slight glitches in Thailand!
As Big Boy says theres loads of information on here, but if you want Dutch company when you arrive there's Hans at the Breakfast Club on Chomsin Road (just over the railway line and out a little way beyond G Supermarket.) And the owner of Pattana Guesthouse was a Dutch guy - I think he is still there.
