Just find a place on either an&b or Booking.com. You can print the reservation details in both English and Thai. And don't stay near the airport like one suggested. Not much going out out there.
Duke is right on soi 13. It's good quality very flexible. Like some others you can get a free sit in session. It's on the third floor of the trendy building.
Duke.... also try the search function at the top of the group page. This Question has been asked many times previously so lots of recommendations there.
